...Week 1 Assignment: The Sperm and the Egg Nathaniel Morris PSY/265 3/18/2012 Nicole Pansey Week 1 Assignment: The Sperm and the Egg Many of us have heard about the birds and the bees. Most parents find this story to better illustrate how conception happens. When a young child asks their parent “Where do babies come from”, a parent may find it hard to look in their young child’s eyes, and describe exactly what happens. The actual scientific process may be harder to explain, but will be more useful for the child when they get older. It would probably be more effective with a variety of visual aids, and preparation in order to present this to an adolescent. Deciding at what age to tell your child the scientific version should depend on the parent. The “birds and bees story” may be more appropriate for a younger child, and the scientific version can be more explained when they are a little more mature. A girl should know about the sexual reproductive system when she starts menstruating. If she is not taught properly, she may not understand what is going on with her body, and may wind up pregnant at an early age. In order to explain the scientific version, first, you would have to start out by explaining the immediate male and female body parts that are involved; the penis and vagina. The inner part of the vagina consists of two ovaries, the cervix, and the uterus that are all connected to the uterus by the fallopian tubes. These are all structures that make up the...

...The Sperm and the Egg: A Story of How Charlie and Penelope Met and Fell in Love PSY/265 March 10, 2013 The Sperm and the Egg Many people have had to sit through the birds and the bees’ explanation of where babies come from. Parents use this because it is a way of explanation without feeling as uncomfortable as one would be if they had to look their child in the eye and describe exactly what happens. This explanation would probably be easier for a parent than going through the difficult task of clarification of the scientific process even though it will be much more useful later on in life. Because every parent has to explain the process no matter the method, it would probably be more effective if the use of visual aids that show each of the steps in how the process works. However, it should be age appropriate and at the parents discretion. Both girls and boys need this information (sexual reproductive system) explained to them in any case because if left in the dark, not only would the girl be at a disadvantage when she starts menstruating, but they could end up being a parent too young in their lives. These things can be a major shock if unprepared. To explain how the scientific version works, one would have to first look at and explain the male and female body parts used; the vagina and penis. The vagina consists of the cervix, uterus, and two ovaries which are connected to the fallopian tubes. All of these complex structures are what makes the woman’s reproductive system...

...Nutrition for Performance CRN: 6978 October 7, 2013 ------------------------------------------------- Testosterone ------------------------------------------------- History & Uses Scott Livingston How did knowledge of testosterone come about? Well, in 1849 Arnold Berthold, a German scientist conducted the first formal experiment pertaining to hormones. He noticed that chickens that were castrated during development grew up to be passive (lacking fighting and mating behaviors) compared to normal roosters. Arnold Berthold decided to implant testes into the abdomens of castrated chickens. The chickens with implanted testes grew up to behave like normal roosters. Thus, Berthold concluded that the testes much secret some sort of substance since they were not connected to nerves. He said, “ The testes act upon the blood, and the blood acts upon the whole organism.” (Berthold, 1849). In 1889 Charles-Édouard Brown-Séquard, a Harvard professor, decided to inject himself with substance containing extracts from guinea pig and dog testicles; he called this concoction a “rejuvenating elixir” (Brown-Séquard, 1889). Brown-Séquard published in The Lancet that his energy, vigor, and overall health were restored, but the effects did not last long; Brown-Séquard attributed this to placebo effect. Because of these findings, Brown-Séquard was mocked by his colleagues, forcing him to give up on his research. In 1927 Fred C. Koch, a professor at the University of Chicago, realized...

...is the major cause of mortality and morbidity in modern societies, among the numerous complications of diabetes. Long standing diabetes has been documented to cause structural and functional cardiac impairment, which was found to lead to ischemic heart disease, cardiomyopathy and congestive heart failure. Previous studies have also shown that diabetics have significantly reduced testicular weights and tubule diameters. The changes in seminiferous tubules ranged from premature sloughing of epithelium to total cessation of spermatogenesis. But recent studies suggest that a combination of bitter leaf (Vernonia amygdalina) and scent leaf (Ocimum gratissimum) extracts could not only reduce the blood glucose level, but protects the heart and testes against impairment and complete destruction due to diabetes. A study by researchers at the University of Calabar published in February 2012 edition of The Internet Journal of Tropical Medicine concluded, “we therefore conclude that extracts of Vernonia...

...Australian demographic, survival rates for testicular cancer have increased in the recent years during “the periods of 1982–1987 and 2006-2010, there is a five-year relative survival increased from 90.7 per cent to 97.6 per cent.” (government, 2014) As well as this, 706 new cases of testicular cancer was presented in Australia during 2010. During this time period, a frequency rate was also conducted which shows a strong increase of 4.2 to 6.5 in a cases of one hundred thousand men who has testicular cancer. Additionally, mortality rates for testicular cancer have also decreased in the past 30 years from 0.5 to 0.1 deaths per one hundred thousand men. The main priority involving testicular cancer would be educating young men on how to improve their health, learn how to look for symptoms and having the confidence to get it checked. The Knowledge of detecting the cancer earlier by young men is proven that Testicular cancer is a highly treatable type of cancer with a very high cure rate which is estimated around 95% if found and treated early. This will then also help boost up the survival rate of cases of testicular cancer presented in Australia. Since testicular cancer is not a preventable cancer in comparison to other cancers such as lung cancer, early dedication and treatment will have...

...ways; however, their sexual response cycles are very similar. There are four phases to the sexual response cycle, beginning with the excitement phase, then the plateau phase, on to the orgasm phase, and finally ending in the resolution phase. One may experience a sexual dysfunction in his or her life, but no fear there are several common methods of treatment to help resolve the issue. One may find it interesting after reading and understanding the sexual response cycle and how each phase works for both males and females. The first phase in the sexual response cycle is the excitement stage. The excitement stage is characterized by erection in the male, vaginal lubrication in the female, myotonia, which cause facial grimaces, spasms in the hands and feet, and then the spasms of orgasm, and increase in heart rate in both male and female. The excitement phase can cause erection in young men as soon as 3 to 8 seconds after sexual stimulation begins. The scrotal skin also thickens, becoming less baggy. The testes increase in size and become elevated. In the female, excitement is characterized by vaginal lubrication, which may start 10 to 30 seconds after sexual stimulation begins. Vasocongestion, which cause erection in the penis and swelling of the area surrounding the vaginal opening, swells the clitoris and flattens and spreads the vaginal lips. The inner part of the vagina expands. The breasts enlarge and blood vessels near the surface become more prominent. Heart rate and blood...

...Essay: Male and Female Reproductive System Do you know how you were born? Do you know how you came to be? The reproductive system is the system that made that all possible. Without the reproductive system you wouldn’t have been born. In order to produce offspring, the male and female reproductive systems have to be different. Each system has different parts, problems and care. Each system have different purposes, the male reproductive system’s function is to produce sperm, while the female reproductive system’s function is to produce ova, store ova and house a fertilized egg. The male reproductive system is divided into two categories: internal and external reproductive organs. External organs are outside the body and internal organs are inside the body. The external reproductive organs are the penis, testes, scrotum, epididymis, and somniferous tubules, which are in the testes. The penis allows liquid waste and semen to leave the body. The testes, which are comprised of somniferous tubules, produce sperm. Sperm mixes with seminal fluids to produce semen. Semen is released through the penis and sperm in the seminal fluid has the ability to fertilize an egg. The scrotum protects and holds the testes and epididymis. The epididymis stores sperm. It also allows them to mature The internal reproductive organs are the vas deferens, seminal vesicles, Cowper’s gland, and the prostate gland. The vas deferens extends from each epididymis. They allow the sperm to leave the scrotum...

...that I had a neurological disease which meant that for eight or more hours a day I lost control of my faculties, bade farewell to the outside world, and was subject to complex hallucinations and delusions – such as being chased by a grizzly bear at Stockport Railway Station – you would think I was in a pretty bad way. If I also claimed that the condition was infectious, you would wish me luck in coping with such a terrible disease, and bid me a hasty farewell. Of course, sleep is not a disease at all, but the condition of daily (nightly) life for the vast majority of us. The fact that we accept without surprise the need for a prolonged black-out as part of our daily life highlights our tendency to take for granted anything about our condition that is universal. We don’t see how strange sleep is because (nearly) everyone sleeps. Indeed, the situation of those who do not suffer from Tallis’s Daily Hallucinating Delusional Syndrome is awful.

Purdue owns the chickens and feed and everything except the waste 3. What is the difference in opinion about chicken manure between Perdue and other large chicken producers and the chicken farmers (represented in the film by Carole Morison)? Carole Morison = "a mess" it’s a negative, purdue should take responsibility; Purdue = “a resource” farmers should consider it a valuable resource 4. Do you agree with Perdue or Carole Morison?

...describe the different phases both men and women experience when sexually aroused. The cycle refers to the “sequence of physical and emotional changes that occur as a person becomes sexually aroused and participates in sexually stimulating activities, including intercourse and masturbation.” WebMD (2005-2011). The cycle is broken down into four different phases. The excitement phase, the plateau phase, the orgasmic phase, and the resolution phase Nevid and Rathus (2005). Below, I will break each phase down and describe how they affect both men and women and the similarities they have. The Excitement Phase The first phase of the sexual response cycle is the excitement phase. In this first phase an engorgement of blood vessels, also called vasocongestion, begins after 3 to 8 seconds for men and 10 to 30 seconds for women after erotic physical or mental stimulation Nevid and Rathus (2005). This is the phase where the body prepares for sexual intercourse. The male testes rise and the skin on the scrotum thickens and tenses. The vasocongestion results in erection for males. The female also experiences vasocongestion by swelling in the clitoris, vaginal tissues, and areas around the vagina. This phase also makes the skin flush and rosy. It is more noticeable in females. Males and female both experience their nipples becoming erect and harden as well as a blood pressure and heart rate increase. Nevid and Rathus (2005) noted that this phase can last for both the female and male from a...
