University Of Phoenix 09 Sexual Response Cycle Sexual Response occurs in four different stages. According to Masters and Johnson, they are excitement, plateau, orgasm, and resolution. It is also characterized by vasocongestion or the engorgement of blood vessels with blood making the genitals and breast swell during the arousal state; the next is myotonia or muscle tension. This causes facial expressions, spasms in the hands and feet, and orgasms. Excitement The first phase is the excitement stage, by which an erection of the penis occurs in males and vaginal lubrication occurring in females.
The Sexual Response Cycle Amanda Turner PSY/210 February 14, 2010 Kathy Smith The Sexual Response Cycle The sexual response 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. The sexual response cycle for man and women have some similarities and some differences. Knowing how one’s body responds during each phase of the cycle can enhance a relationship and help one pinpoint the cause of sexual dysfunction (Cleveland Clinic, 1995). The sexual response cycle is divided into four phases: excitement, plateau, orgasm, and resolution. Both men and women experience the four phases of the sexual response cycle, although the timing is usually different.
Human Chorionic gonadotropin (hCG) is a hormone that women use to cause ovulation and treat infertility. Men use this hormone to increase their sperm count. Young boys can also use this hormone if their testicles have not dropped into the scrotum normally. This infertility, low sperm count, and testicles not dropping properly can be caused by a pituitary gland disorder. hCG effects the hormone LH (Luteinizing hormone) and the target tissue is the ovaries in women and testis in men.
Additionally, the perceived hypovolumic status causes the release of antidiuretic hormone (ADH) from the posterior pituitary. ADH increases water reabsorption in the kidneys, which further contributes to increased volume and increased BP (McCance & Huether, 2010). 2.) What tests indicate glomerular function? Serum creatinine concentration, cystatin C plasma concentration, and BUN levels indicate glomerular function (McCance & Huether, 2010).
Many people using steroids can get liver cancer, psychological defects, have organ damage, hormonal changes, and sometimes infertility. They can increase the risk of tearing tendons, developing enlarged breasts in males, and an increase of facial hair in females. Most minor effects can lead up to life threatening or possibly even death. Many major and long-term problems include urinary trouble, aggression, paranoia, insomnia, depression, nausea, vomiting, high blood pressure, heart disease, aching joints, liver cancer, and liver damage. (Weebly 6) The liver can be over worked by consuming a great amount of steroids, slowing the bile movement through the liver which can increase the chances of a tumor developing.
Describe and evaluate hormonal mechanisms in aggression. (8 marks + 16 marks) The male sex hormone testosterone is thought to increase levels of aggression from young adulthood onwards. It is thought that testosterone may influence areas of the brain that control behavioural reactions, such as the amygdala and the hypothalamus. Testosterone also influences the levels of other hormones which are thought to be involved in aggression, such as vasopressin. The link between testosterone and aggression may explain why males are generally more aggressive than females: males produce much higher concentrations of testosterone than females, and this may therefore lead to higher levels of aggression.
There are many more causes of sexual dysfunctions that consist of cultural differences, religious beliefs, and the most common, health problems or the medications taken from these problems. In all cases of sexual dysfunction patients are treated with sex
Males were in constant competition for food and for possible mates. They attracted their possible mates by their sexual dimorphism, and proved themselves worthy by their strength. In particular female species had a high ranking; they would harass lower ranking females. For every species, certain sexual characteristics were favored than others. During a female’s sexual peak they display visible characteristics of readiness to reproduce.
Nurture; is it natural for men and woman to be attracted to the same sex? Or does the environment or society cause a person to seek companionship from the same sex? According to researchers they have examined the brains of both a heterosexual and a homosexual male and female and have determined that the hypothalamus (the organ in the brain that is responsible for sexual behavior) was much bigger in the homosexual subjects than in the heterosexual subjects. They believe this was a cause of an increased amount of early levels (probably prenatal) of estrogen (a natural or artificial female sex hormone responsible for the development of female sexual characteristics) in the men and androgen (a natural or artificial male sex hormone responsible for the development of male characteristics) in women. Also it is the possibility that a male receives too little androgen at birth and the female receives too little estrogen at birth causing the homosexual and the lesbian behavior.
There is an increased risk of breast cancer and blood clotting as well as heart attack and stroke. Increased blood pressure, migraines, and gallbladder disease are also risks. Women are fertile briefly during their menstrual cycle, just before ovulation. Studies have established that both partner preferences vary according to knowable hormonal fluctuations related with this cycle. Ovulating women prefer more masculine, dominant and competitive males.
