King Arthur Essays (397 words) - Holy Grail, English-language Films

King Arthur Portayal of the Middle Ages is thought to be made of magnificent castles, beautiful clothing, great kings and queens everything and everyone perfect. No proof of the. Towns back then were not pretty. Dirt thrived in cities there were diseases and crud everywhere. Communities during the Middle Ages were not orderly. They were probably outright chaotic. As far as the king goes, he probably did not do much to help the fairness of towns. Arthur, such a great king. He would not have existed back then. Kings during the time of The Once and Future King were mostly insane, or cruel, or just should never have been remembered. No king ever did so many things that they would have stood out so much as Arthur would have. Lancelot was a great fighter and was brave, fair and set on doing the right thing not many knights were like that. Lancelot lived so easily he could get away with anything, and would fight for anyone as long as it was for the well-being of someone good. All blood and gore, no fancy romantic, pictures of life. It was dirty, and not always so ideal. As obvious as this is, it should be pointed out. The Once and Future King contained a magician, as wonderful as Merlyn is, and knowing that the story could not have taken place without him he could not have existed. But, unfortunately, reality just swipes him away. In The Once and Future King there is a great part that goes on the knights of the Round Table. The thing thatbrings out the untruth of it. There may have been a few well behaved knights during the actual Middle Ages, but not enough to create a club and be so influential that the entire kingdom knew of you. Most knights were feared not desired. The knights in reality went around to towns pillaging and raping-basically destroying anything and everything. The novel places knights in this innocence picture, a beautiful, yet completely absurd representation. All in all The Once and Future King is basically out of nothing, although the authors did a very nice job of creating a fairy tale out of a horrendous time. Most people like to pretend that the early Middle ages were great but facing reality, you just can not believe it. Too much dirt, too much violence all fighting no love and beauty. The time period can sprout love and beauty, given the right amount of spice, though. As The Once and Future King did.

Biography of Steven hill essays

Biography of Steven hill essays After Geoff left us, I never thought Kirksville soccer would ever be the same. Fortunately I was wrong. Steven Hill was his name, our teams savior, and this is his story. I had first met Steven late in his Junior year. We were both on the track team together. Though we were not well aquanted, Steves spirit was then made obvious to me. Steve was a hard worker, of this I had no doubt because not once had I ever heard him complain. Steve had a tendancy to stay quiet until our teams moment of need. He would slowly and suddenly arise from the dust as if he were a mesenger of a distant king, delivering a few short, emotional, and to the point words to stir our team to victory. Steve kept me fighting when I was down. This hidden talent of his would only make itslef more brilliant in the year to come. 2002, Stevens senior year began at Kirksville highschool. Track not being enough for the obviously gifted athlete, Steve decided to persue soccer, the sport of the Gods. Recognizing Steven from the previous year, I engaged him in conversation. Our dialect eventually turned to the fact that this was Steves first year of soccer, which surprised me. Where a weaker man would have been intimidated, Steve took the challenge as nothing but another simple game for him to defeat, Soccers just like basketball right, only the nets bigger, and you cant use your hands. As the season progressed, Steves skill was made as bright as the Star of Jeruselem, calling the wise men to worship the Christ. This incredible power was of coarse young and unpolished but it reminded me of another that had left the team long ago. I confronted Steven about how a first year soccer player could possibly be so skilled, and in his simple yet magnificent way, he told me, I heard somewhere once, that if you have a little cordination, and a lot of will power, you can do anything you se ...

Managing organisational behaviour Essay Example | Topics and Well Written Essays - 2500 words

Managing organisational behaviour - Essay Example As a result of developing and implementing management practices to successfully manage human resources is critical for organizational achievement. The highly competitive global environment of the 21st Century demands managers to use proactive practices and methods to managing behavior for the purpose of creating a competitive advantage (Bhattacharya & Wrights, 2005). Theoretically the science of managing organizational behavior has the responsibility of using human resources to fulfill an organization’s goals and objectives. This premise and the development of the capability of the human resources aids in accomplishment of goals. Certainly not without challenge managing people (human resources) effectively is the process of comprehending human behavior, knowing how to motivate, and enable others to become what he or she is capable of becoming with the intention of fulfilling the group’s strategic objectives. The purpose of this paper is to offer suggestions as to the at tributes and necessary skills an effective manager/leader needs to proactively manage human resources. ... is not a release of control and power by management, but is a method in which management gains additional control over behavior in the organizational culture as a result. Organizational Behavior Understanding organizational behavior enables managers to use human capital and other resources more effectively. The ability to understand his or her relationship with workers and the significance of the interaction is foundational in understanding how to effectively manage organizational behavior. The interaction between managers and workers in the culture directly influences the outcomes of behavior within the culture. Schermerhorn, Hunt, and Osborn (2003) assert â€Å"Organizational behavior (OB) is the study of individuals and groups in organizations† (p. 4). Kreitner and Kinicki (2003) declare â€Å"Organizational behavior is an interdisciplinary field dedicated to better understanding and managing people at work; organizational behavior is both research and application oriented † (p. 12). The two descriptions or definitions include the understanding of coordinating people in structured settings for the purpose of accomplishing specific goals. Kreitner and Kinicki (2003) offer that the task of managing people requires knowledge and the ability to apply the principles of the social disciplines of psychology, management, sociology, statistics, economics, human stress management, and others (p. 13). The list of disciplines reaffirms the depth of knowledge of human behavior that is necessary for managers to manage successfully. Effective managers comprehend how to interpret human behavior applying the appropriate principles from the tools of the applicable social science. By using the tools managers are able to resolve conflict within the environment, motivate workers to higher

Critically Analyse the Claim that Humans Are Political Animals Essay

Critically Analyse the Claim that Humans Are Political Animals - Essay Example This paper stresses that given the fact that individual human beings are not in any position to carry out their naturally defined functions without the city-state, the so given state is therefore naturally precedes the individuals in every aspect. In regards to the above mentioned arguments then, it is clear that every human being or individual has the natural impulse for a community which is political especially with the consideration that the city-state was created out of the intelligence of human beings. They then end up living a political life while in nature they are animals. Man is known to have an innate proclivity to always participate in several public activities and deal with others in the city. Associations and other bonds are then created as men live together in partnership due to the natural tendency to interact and socialize with other men. This rpeort makes a conclusion that as much as the several theorists try to explain the political naturalism in human beings, there is no concern or any consideration expressed on the part of the city-state’s modern liberalism. There is no explanation given on the freedom of individuals who participate in the city-state and protective provisions for their own private life from the exposition of the entire public. Aristotle’s arguments and justification on communitarian politics gives priority to the well-being of a community. Other modernists also argue on the basis of humans being conjugal and dependent on each other and thus conclude that establishing households, interacting and socializing among individuals makes one a complete human being. In that case, individual liberty does not win in context of any city-state just as freedom and private ownership does not exist for animals.

Marketing Analysis Of Virgin Media Marketing Essay

Marketing Analysis Of Virgin Media Marketing Essay Services marketing are a form of marketing which focuses on selling services. Services can be tricky to sell and the marketing approach for them is much different than the approach for products. Some companies offer both products and services and must use a mixture of styles; for example, a store which sells phone also tends to offer services such as helping people select phone as contract and providing broadband service and phone repair. Such a store must market both its products and the supporting services it offers to appeal to customers. Virgin Media is an innovative new media company that was formed as a result of a merger between NTL and Telewest and then a re-branding as Virgin Media. Its main strength lies in the branding and the innovation that the name Virgin offers. Internally, Virgin Media is the only company in the United Kingdom that offers all four of the main media services, i.e. digital television, broadband, fixed line telephone and mobile phone packages. The ability to offer these products all together in one bundle is the unique selling point of Virgin Media and clearly sets the company apart from its competitors. Swot analysis is the most important and first stage of planning. It is a feedback mechanism to make new strategies for any organisation. Strengths, Weaknesses, Opportunities and Threats are the four components of a swot analysis. Weaknesses and Strengths are correlated and examine the internal part of the business analysis whereas Opportunities and Threats deal with the external environment of business operation. Weaknesses and strengths refer to aspect of marketing, finance, manufacturing or organisational structure. Swot analysis helps clarifies the objectives of the organisation Strengths In offering these combined services, the company has substantial economies of scale as it is able to combine many of its generic roles such as administration and finance, thus allowing the company to price more competitively for the benefit of its customers. Due to its perceived leading brand name in the media, Virgin Media has managed to secure an ongoing contract with Sky, extending further still its inclusive offering to its customers. Technical ability and infrastructure are also two of the key internal strengths of the company, which have been exploited to produce a market leading position. Weaknesses Despite this, the company does have some internal weaknesses that need to be managed. The merger between NTL and Telewest is still relatively new and there are cultural clashes between the two styles and the emerging Virgin style. In recent years, there have been several redundancies and outsourcing of customer services, in an attempt to bring down costs. This has resulted in a degree of unsettled behaviour and lack of loyalty from staff. Due to the size and complexity of the growing organisation, there are likely to be ongoing conflicts which will need to be managed if this cultural shift is not to impact on the customer experience. Opportunities and Threats Externally, the opportunities and threats facing Virgin Media are ever changing. The media sector is developing an exceptionally fast pace, resulting in both opportunities and threats for companies such as Virgin Media. Opportunities are widely available for Virgin Media, predominantly in offering value added services such as online gaming or more reliable broadband connections. Bundling these media services together, as Virgin Media has already done offers yet further opportunities within the media sector, in terms of grasping greater market share. Consumers like simple, one-stop shopping when it comes to the media options available; this is something that Virgin Media can continue to exploit, particularly now that it has signed an agreement with Sky. Threats to Virgin Media come from other similar media companies such as Orange or BT who remain as large players in the market. In particular, Virgin Media is rumoured to have difficulties with its infrastructure reliability, which could potentially allow competitors such as BT to increase market share. The media sector as a whole is extremely fast moving; therefore, the main threat is that Virgin Media may fail to keep pace, thus losing its customer base to another more innovative company. The flower of service Facilitating elements(services) Information: Customers often require information about how to obtain and use a product and services. They may also need remainders and documentation. Example, Of virgin broadband information services are: Direction to service site and using instruction, warning and insurance, terms and condition of services. Order taking: Many goods and services must be ordered or reserved in advance. Customer needs to know what available and may want to secure commitment to delivery Billing:How much do I owe you? .Customers deserve clear, accurate and intelligible bills and statements. Payment: Customer may pay faster and more cheerfully if Virgin makes transactions simple and convenient for them. 2) Enhancing services: Consultation: Value can be added to goods and services by offering advice and consultation. Safe keeping: Customers prefer not to worry about looking after the personal possessions that they bring with them to a service site. Exceptions: Customers appreciate some flexibility in a business when they make special request. They expect it when not everything goes according to plan. Hospitality: Customers who invest time and effort in visiting a business and using its services deserve to be treated as welcome guests. User Preparation When implementing new system, it is important that personnel, employees, managers and others in the organization are prepared for it. This process is also called process of readying the decision makers, managers, employees, and stakeholders for a new system. In this regard, user training becomes very essential, because without it the success of the system cannot be guaranteed. This process of user preparation is planned and executed properly and involved a lot of arrangement, and consideration (Stair Reynolds, 2008). Virgin Media, the UKs leading fibre-optic broadband provider currently has almost 60,000 SME and public sector broadband clients, but has announced that it is looking to grow this significantly. Virgin Media has unveiled plans to target the small and medium business customers of its rival broadband giant BT. The move comes soon after BTs commitment to undercut Virgin Medias residential super-fast broadband prices, with its new fibre-optic broadband service which BT is rolling out this year. There is a very big market up for grabs, as small and medium-sized enterprises (SMEs) spend about  £18bn a year on IT and telecoms. Virgin Media currently have revenues of about  £600m pa from business broadband customers and this is forecast to rise to about  £1bn pa in three to five years. Virgin Media chief operating officer Andrew Barron said: This is another step forwards. Weve been working in the business division for 18 months on getting the business processes to the right level. Weve improved it dramatically. We can use the fibre-optic network to differentiate ourselves. Marketing communication Mix: The marketing mix is the set of controllable tacticle marketing tools that the firm blends to produce the Response it wants in the target market (Melewar. T.C., Saunders.J, 2000) Marketing communications are the means by which firms attempt to inform, persuade, and remind consumers directly or indirectly about the products and brands that they sell. A company s total marketing communication mix also called promotion mix (Kotler, 2005) consists of specific blending of advertising, personal selling, sales promotion, public relations, and direct marketing tools that are used by company to pursue its advertising and marketing objectives. The marketing communication activities which contribute to the marketing of any new or existing product: by creating awareness of the brand; linking the right associations to the products image in the consumers memory, facilitating stronger consumer-product connection etc. Current extended marketing mix marketing mix. People People is one of the elements of service marketing mix. People define a service.. In case of service marketing, people can make or break an organization. Thus virgin media nowadays are involved into specially getting their staff trained in interpersonal skills and customer service with a focus towards customer satisfaction. In fact many companies have to undergo accreditation to show that their staffs are better than the rest. Definitely a USP in case of services. Process Service process is the way in which a service is delivered to the end customer. The process of a service company such as virgin media in delivering its product is of utmost importance. It is also a critical component in the service blueprint, wherein before establishing the service, the company defines exactly what should be the process of the service product reaching the end customer. Physical Evidence The last element in the service marketing mix is a very important element. As said before, services are intangible in nature. However, to create a better customer experience tangible elements are also delivered with the service. Physical evidence is used as a differentiator in service marketing. This is the service marketing mix (7p) which is also known as the extended marketing mix Position Positioning in different areas is not always easy (I can say it is too difficult). Virgin Group was aware of the difficulties so they had to think about the Virgin brand name. They have never entered in a business before doing solid researches and analysis. They have reviewed the industry and tried to look from customers eyes. They were aware of the trade-offs they had to think before entering a new business venture and they have never underestimated the risks behind new entrance. Advertising Virgin Media launched to much fanfare in February 2007, with a public relations event and an expensive advertising campaign which covered major UK television channels, newspapers and billboards. In an effort to increase awareness of the group and its services, Virgin Medias campaign used bright red colours to portray its brand image. Recent[update] television advertising featured actress Uma Thurman and comedienne Ruby Wax, and currently[update] features actor Samuel L Jackson, whilst the print advertising features bold typography. Virgin Media also sponsored the Channel 4 reality TV show Big Brother until the end of the ninth series. Virgin Media Business/ On Thursday 11 February 2010, Virgin Media announced that its business division would be rebranded as Virgin Media Business with immediate effect. The company, which had been operating as ntl:Telewest Business, is now the largest B2B brand in the Virgin Group. This marked the end of the NTL and Telewest being used by the company. Virgin Media Business is the UKs only telco with a national fibre optic Next Generation Network. Organisations working with Virgin Media Business include London City Airport, Arqiva, Hampshire and Isle of Wight Partnership and South West Water. Consumer behaviours Understanding how consumer behaviour is changing will be an important requirement of Virgin Medias upcoming music offering and, should they become law, the Governments legislative proposals will also require measurement of the level of copyright infringement on ISPs networks. Deticas CViewà ¢Ã¢â‚¬Å¾Ã‚ ¢ technology potentially offers a non-intrusive solution which enhances our understanding of aggregate customer behaviour without identifying or storing individual customers data. Consumer Segment We face intense competition from a variety of entertainment and communications service providers, which offer comparable broadband internet, television, fixed line telephony and mobile telephony services. In addition, technological advances and product innovations have increased, and will likely continue to increase, the number of alternatives available to our customers from other providers and intensify the competitive environment. See Risk Factors-We operate in highly competitive markets. However, we believe that we have a competitive advantage in the U.K. residential market due to the superior technical capabilities of our cable network over the network of the incumbent BT, which many of our competitors rely on to provide their services. We also face intense competition in the mobile telephony market, primarily driven by increased pricing pressure from both established and new service providers, evolving customer needs and technological developments. We offer most of our products on a stand-alone basis or as part of bundled packages designed to encourage customers to subscribe to multiple services. We offer broadband internet, fixed line telephony and mobile telephony and data services throughout the U.K., and currently offer television services exclusively in areas served by our cable network Segmentation, Targeting, Positioning (STP) Before start think about marketing (4P), you must understand what is STP. Terms of STP include : market strategy; target markets; positioning; market segmentation and target markets; market segmentation and demographics Segmentation Segmentation : Identifying all segments for the product/service. Many of the resources listed in module 3 will be helpful to you when you develop segments. To be useful, segments should be: Measurable Accessible (can you reach them) Profitable Distinct from one another the objective of segmentation is to find attractive markets. Strategies include Break market into components Regroup into market segments Select which segment to target Targeting Virgin Media is currently number two in the home broadband market in the UK, but it obviously doesnt want to be left behind when it comes to broadband on the move. The company has its own-brand mobile phone service, so its wasnt that much of a leap for it to add mobile broadband into the mix. Virgin is offering mobile broadband via a number of different deals. For example, if youre already a Virgin customer using its XL (20Mb) or L (10Mb) cable broadband packages or its ADSL Bundle 1 offering, you can get mobile broadband with a 1GB usage allowance for an additional fiver a month. If youre on one of the lower-end home broadband deals you can get the same package for a tenner a month. However, for this review were looking at the standard retail pack which targets people who dont already have a Virgin service. This deal costs  £15 a month on an 18-month contract for a 3GB monthly download allowance and a free USB modem Positioning. Positioning is an essential component and skill in good marketing. Perceptual maps are used to determine the position of a product, firm, person, service or idea. Positioning maps or perceptual maps can be simple, yet very effective marketing tools. One definition of Positioning Theory is: the science of perceptual strategy. It is based on a theory that strategy can only be planned in the mind of the consumer, not the marketplace*. It is important to understand the levels of competition because positioning applies at all levels of competition. For example: Product Level Corporate Level Industry Level The STP Process The growing use of the STP process has occurred as a direct result of the prevalence of mature markets, the greater diversity in customer needs, and the ability to reach specialized or niche segments. As such marketers are increasingly segmenting markets and identifying attractive segments (i.e. who to focus on and why?), in order to identify new product opportunities, develop suitable positioning and communications strategies (i.e. what message to communicate), and effectively allocate resources to key marketing activities (i.e. how much should we spend and where?). Organizations will often commission segmentation research when they want to re-scope their marketing strategy, investigate a declining brand, launch a new product, or restructure their pricing policy. Organizations operating in highly dynamic environments seek to conduct segmentation research at regular intervals, to keep in touch with changes in the marketplace. STP refers to the three activities segmentation, targeting, and positioning SOURCES 1. Virgin Media, fourth quarter 2007 results presentation, February 2008. 2.

By 112 Study Guide

Silence of the Bees: †¢ How do bees communicate? Bees communicate through dance (the waggle dance). A methodic combination of buzzing, moving the behind in a figure-eight fashion that informs other bees about pollen/ food that is found in a particular area. †¢ Why are bees so important to the U. S. agriculture industry? Honeybees are the most important pollinator on the planet. They pollinate crops, which in turn creates food to eat. What percentage of the industry do bees account for? They account for one-third (more than 30%) of the food that is produced in America.They pollinate at least 100 of our most important crops (cotton, fruits, vegetables, nuts, seeds, etc. ) †¢ What are some natural dangers to the bee industry? Natural dangers to the bee industry would be natural disasters (wildfires, hurricanes, tornados), wild animals (mainly bears) †¢ What is considered adequate pollination? †¢ What is CCD? Colony Collapse Disorder. This is a phenomenon in whic h worker bees from a beehive/colony abruptly disappear. When did it become a noticeable problem? Winter 2006 is when the issue was noticed, but it wasn’t until the following spring that it was named CCD and was being researched heavily. What are characteristics of CCD versus other hive disturbances/illnesses? The bees are completely vanishing, as opposed to a mite infestation where the bees would be crawling on the ground. Also, other insects leave infected hives untouched †¢ What types of crops are affected by CCD? A lot of crops are affected, all the crops that are pollinated by bees! In the video, blueberries, oranges, apples, cantaloupes (travel 55 hundred miles per year). †¢ Where do we get new bee colonies in the U. S. for industry use? We import bees from Australia.The Australian bees are the bees that could have potentially carried CCD to the US. †¢ What are factors thought to possibly contribute to CCD? Pesticides (which impair bees ability to learn ca using them to forget their way back to the hive), cell phones interfere with be navigation, mites, or a pathogen causing this rare occurrence are all factors that scientists have thought to contribute to CCD †¢ If CCD continues, what would happen to the agricultural industry? Ultimately the agricultural business would die, food expenses would rise, unless we are willing to use hand pollination. What if any crops would be left? The crops pollinated by the environment (wind or rain) Examples are corn wheat, rooted crops (potatoes, carrots, etc. ) †¢ What is the approximate lifespan of worker bees? The approximate lifespan of a worker bee is 28-35 days †¢ What sex are worker and drone bees? Worker bees are female (collect pollen and pollinate other flowers) and drone bees are male (sole purpose= mate with queen) †¢ What is HFCS? High Fructose Corn Syrup †¢ According to the case study, what impact might HFCS have on CCD? If not stored properly, substances within HFCS will form HMF (hydroxymethlfurfural). According to the article used in the case study, what major issues/concerns were addressed by the authors? The first issue is how commercial workers are storing the HFCS in transportation. Also, how the apples will get pollinated if the bees keep dying/disappearing. †¢ What are the advantages to the commercial use of HFCS? It is easy to store if properly stored, stable shelf life (will hold for a long period of time), and cheap (because we have a lot of it; it is easy to find and purchase). It is used to sweeten foods. Earthworms: †¢ Which side of the worm did we cut into? We cut into the dorsal side of the worm (the back).The dorsal side of the worm was smooth and darker than the ventral side (the underside) †¢ Know the purpose of all the organs we discussed. Dorsal side is dark and feels smooth Ventral side is lighter and has a rough feel caused by setae Setae – Bristles that aid in providing traction for movement M etameres are the body segments that are internally separated by septa Clitellum – the light-colored cylindrical structure close to one end of the worm -a glandular organ that produces mucus for copulation -secretes the cocoon into which eggs are deposited â€Å"Head† or Anterior end of worm is the one closest to the clitellum – at he tip is the mouth Posterior or Caudal – anus (where waste is removed) is located here. Oviducts –small openings located on the ventral side where eggs emerge; followed by sperm ducts (located on segments 14 and 15) Cerebral Ganglion (â€Å"brain†) – located at the cranial tip of the worm Aortic Arches (heart) – 5 around the esophagus; pump blood in a closed circulatory system †¢ What is coelomic fluid and why is it important for earthworms? The coelomic fluid is located in the coelom (body cavity) that acts as a hydrostatic skeleton to support the body and aid in movement.What is the typhlosole ? The typhlosole is the fold or ridge in the intestine that increases efficiency. †¢ Why do we dissect Earthworms? We dissect earthworms because they are a great introductory specimen. They lack a skeleton which makes dissection easier. They have some organs of more highly evolved organisms such as a closed circulatory system and simple digestive system. †¢ What type of circulatory system do earthworms have? Earthworms have a closed circulatory system with hemoglobin and amebocytes. They are the simplest organism with a closed system.Blood is pumped by a heart through vessels and doesn’t fill the body cavity. †¢ What do earthworms eat? Earthworms eat organic matter such as leaf, litter, animal waste, etc. †¢ How do earthworms obtain oxygen? Earthworms must absorb oxygen via diffusion through their moist skin because they don’t have any respiratory organs. How does their habitat affect this? Earthworms are burrowers found within rich soil which stays moist, aiding in the earthworms obtaining of oxygen. If earthworms dry out or the soil dries out, they die (suffocate) because oxygen can’t diffuse into their skin.These creatures have adapted by doing two things: 1) slowing down bodily functions during dry spells to conserve water 2) they can lose up to 70% of their body water before dying in this condition. †¢ How do earthworms reproduce? Earthworms reproduce sexually even though they are hermaphrodites. During mating, both worms exchange sperm to fertilize the eggs. This is an advantage because it creates more genetic diversity. †¢ Be able to identify structures in drawings like those in the handout. [pic] [pic] [pic] †¢ Know directional terms. Posterior – towards the caudal end (foot/tail)Anterior – towards the forward end (head) Dorsal – back side of the animal Ventral – bottom side of worm; tummy side †¢ Know the definitions of the external & internal structures we discus sed while dissecting the earthworm. EXTERNAL †¢ Dorsal side is dark and feels smooth †¢ Ventral side is lighter and has a rough feel caused by setae †¢ Setae – Bristles that aid in providing traction for movement †¢ Metameres are the body segments that are internally separated by septa †¢ Clitellum – the light-colored cylindrical structure close to one end of the worm o a glandular organ that produces mucus for copulation secretes the cocoon into which eggs are deposited †¢ â€Å"Head† or Anterior end of worm is the one closest to the clitellum – at the tip is the mouth †¢ Posterior or Caudal – anus (where waste is removed) is located here. †¢ Oviducts –small openings located on the ventral side where eggs emerge; followed by sperm ducts (located on segments 14 and 15) INTERNAL Reproductive System: †¢ Know the path taken by sperm to exit the male body during ejaculation. Be able to explain includi ng all glands and secretions on the path.At the time of ejaculation sperm leaves the epididymis via the vas deferens. As it goes through the vas deferens to the urethra it picks up the following fluids in order: nutritive fluid from the seminal vesicles ( milky alkaline fluid from the prostate ( mucous fluid for lubrication from the Bulbourethral gland/Cowper’s gland. †¢ Why are so many sperm produced? So many sperm are created because not all of the sperm make it to the egg. Many die trying to fight their way through the acidity/stickiness of the female reproductive organs.Sperm must work extremely hard to reach the egg and once it gets to the egg it must continue its rough journey breaking through the zona (hard outer shell of the egg) †¢ Know the definitions of male and female reproductive terms discussed in class. MALE= penis Penis – composed of 3 cylinders of erectile tissue: o Corpus cavernosa – 2 cylinders on dorsal part of the penis o Corpus Sp ongiosum – surrounds the urethra; distal end is enlarged to form the glans penis Scrotum – thin membranous sac that houses testes. Testes o Produce approx. 200-300 million sperm/ 24hrs in each testes o Approx. 700 ft. f seminiferous tubules – 80% of testes. o Essential male organs o Proper function is dependent on temperature Epididymis: o Located over the top back portions of the testis o Store immature sperm Vas Deferens – Tube through which sperm leave the epididymis during ejaculation Seminal Vesicles – add nutrient rich fluid for sperm Prostate: o Golf ball size o Produces a milky alkaline fluid – possibly to help with proper function of the flagella Bulbourethral Gland/ Cowper’s Gland– produces a mucous fluid to act as lubrication during ejaculation.

Ova production begins about the 7th week of embryonic development ? At birth each ovary contains approx. 1 million follicles with the potential to develop into eggs ? Approx. 80% of follicles degenerate by puberty leaving about 400,000 ? Only about 400 eggs will mature throughout reproductive life of female †¢ Why do so many sperm not survive?So many sperm don’t survive because of their short lifespan and the environments each individual sperm encounters after entering the vagina. For example: the vagina is acidic so approx. 25% of the sperm die immediately upon entry. Once the environment becomes fluid again, the sperm remain viable for 28-48 hours before sperm run out of nutrients and starve. The female defense system attacks sperm as foreign invaders. And the sperm must make it through the cervix (usually thick mucus) which secretes a protein fluid called musin. Once it gets through the cervix, it enters the uterus moving through the uterine cavity.The flagella of the sperm must work harder to go up the fallopian tube (swimming against current) finally reaching the EGG! 60% of sperm is less than perfect. †¢ What is the difference between sperm and semen? Sperm is the male sex cell of semen that fertilizes an egg, whereas semen is the combination of fluids and sperm that leave the penis via the urethral opening. Semen is sperm mixed with nutritional fluid from the seminal vesicles, alkaline fluid from the prostate, and mucus from the Bulbourethral/cowper’s gland †¢ Be able to identify and label the male anatomy. [pic] Be able to identify and label the female anatomy. [pic] [pic] †¢ What are the male and female sex organs? Know the composition/purpose of each and be able to compare the two. MALE= penis Penis – composed of 3 cylinders of erectile tissue: o Corpus caverno sa – 2 cylinders on dorsal part of the penis o Corpus Spongiosum – surrounds the urethra; distal end is enlarged to form the glans penis Scrotum – thin membranous sac that houses testes. Testes o Produce approx. 200-300 million sperm/ 24hrs in each testes o Approx. 700 ft. of seminiferous tubules – 80% of testes. Essential male organs o Proper function is dependent on temperature Epididymis: o Located over the top back portions of the testis o Store immature sperm Vas Deferens – Tube through which sperm leave the epididymis during ejaculation Seminal Vesicles – add nutrient rich fluid for sperm Prostate: o Golf ball size o Produces a milky alkaline fluid – possibly to help with proper function of the flagella Bulbourethral Gland/ Cowper’s Gland– produces a mucous fluid to act as lubrication during ejaculation. FEMALE= vagina ? Folds of tissue that are covered with hair on the outside ?Smooth and moist inside folds to cap the ends of the corpus carvernosa (similar tissue to that of the corpus spongiosum in males) ? Located between bladder and rectum ? Capable of great expansion to allow fetal development ? Lined with endometrium ? lead from uterus to ovaries ? Have fimbriae extensions at end by ovaries to catch released eggs. ? Ova production begins about the 7th week of embryonic development ? At birth each ovary contains approx. 1 million follicles with the potential to develop into eggs ? Approx. 0% of follicles degenerate by puberty leaving about 400,000 ? Only about 400 eggs will mature throughout reproductive life of female †¢ What is the purpose of each reproductive structure covered in class? Answered in the above question. †¢ Know all of the glands and organs involved in the endocrine system along with their functions †¢ Consists of glands that produce hormones to regulate: growth, reproduction, metabolism, personality, etc. †¢ Hormones – highly specialized chemi cals that act as messages to organs; carried in the blood stream throughout the body. Pituitary gland (Hypophysis) – produces growth hormone and regulatory hormones †¢ Thyroid – produces thyroxin which regulates metabolic rate †¢ Hypothalamus – secretes regulatory hormones †¢ Parathyroid – regulates calcium and phosphate levels in blood †¢ Adrenal gland – produces corticosteroids, epinephrine (adrenaline), and norepinephrine †¢ Pancreas – islets of Langerhans produce insulin; rest of pancreas produces digestive enzymes †¢ Ovaries – Estrogen, progesterone †¢ Testes – testosterone †¢ How many eggs are matured during one female cycle?Females are born with 1,000 eggs and over a lifetime only 400 eggs reach maturation, but during ONE female cycle a SINGLE is matured and sent out to be fertilized. †¢ How long is an average female cycle? An average female cycle = 28 days †¢ Know the ph ases of the menstrual cycle in detail. o Average of 28 day cycle o Involves release of mature egg, shedding of old endometrium and formation of new endometrium o Follicular phase – first 14 days of cycle ? 1st week: old endometrium is shed (menstruation); follicular development begins ? nd week: formation of new endometrium; follicular development continues ? Ovulation: release of mature ovum around the 14th day; egg has approx. 24 hrs. to join sperm. o Luteal phase – endometrium continues to prepare for possible implantation of embryo o If implantation does not occur by the end of the 28 day (average) cycle then menstrual bleeding occurs and the cycle begins again. †¢ Know the embryonic and fetal development discussed in the power point, video, and in your book. -Blastocyst – 5 days after conception -Implantation occurs within 10 days -4 weeks = arm buds, beginning of eyes 5 weeks = nose -6 weeks = leg buds embryo< 0. 5 inches -7 weeks = ? inch; clearly de fined fingers, visible internal organs and eye lenses -8 weeks = well defined fingers and toes -10 weeks = embryo=fetus; can move; approx. 2 inches long -14 weeks = fetus can bring hands together and suck thumb -15 weeks = sensory organs are almost complete -16 weeks = can actively turn -Fetal respiration = baby â€Å"breathes† fluid in and out. †¢ What is spermatogenesis? The production of sperm begins between the ages of 9-12 †¢ Know the structure of sperm and how/where they form and develop. pic] -Sperm is manufactured in the testes (testicle) in the seminiferous tubules. -Immature sperm are stored in the epididymis until ready for ejaculation. -Haploid cells (23 chromosomes) -Comprised of general three parts: headpiece, midpiece, flagellum †¢ What is the average production rate (may be a range) of sperm in a healthy male? More than 400 billion sperm is produced in lifetime and 200-300 million sperm produced daily. In normal semen, there is approx. 39 millio n (range from 33-46 mil) sperm/ejaculation
