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.
Here we look at how each phase of the sexual response cycle works. The first phase of the sexual response cycle is the Excitement phase. This phase includes thoughts, fantasies, and motivation to engage in sexual activity (Benuto, 2009). Vasocongestion during the excitement phase can cause erection in young men as soon as 3 to 8 seconds. The testicles swell, his scrotum tightens and the male begins secreting a lubricating liquid.
Angiotension II causes vasoconstriction, which raises the blood pressure. Angiotension II also stimulates aldosterone release from the adrenal gland. This leads to increased sodium reabsorption by the kidneys, which causes water to follow it, which then increases intravascular volume. The increased vasoconstriction and increased blood volume raise the blood pressure. Additionally, the perceived hypovolumic status causes the release of antidiuretic hormone (ADH) from the posterior pituitary.
stroke volume increases dying exercise to increase circulating blood in the body system in order for the body to respond to exercise appropriately. 5. Discuss the importance of the change in CO with exercise? cardiac output increases due to the increase in heart rate and stroke volume during exercise 6. Restate your predictions that were correct and give data from your experiment that support them.
My temperature increased because of the high amount of heat I produced. So basically the mitochondria in my cells helped my body to turn nutrients and oxygen into energy. So every time I contracted my muscles during the
The force of the isometric contraction increased as the muscle load increased. 9. Which would be a better predictor of increase in force of contraction, change in sEMG amplitude of spikes or change in sEMG frequency of spikes? Change in sEMG frequency of spikes. Discussion 1.
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.
When a male goes through puberty, testosterone is used by the body muscle faster, deepen the voice, and grow hair where it used to be bare. A downside of steroids is that
These phases are the starting point to the sexual response cycle and even though similar in description, men and women have many different bodily reactions. Men for example have the blood rush to their genitals engorging the penis with blood, the testis swelling, and the scrotum tightening allowing the testis to rise. Yet in women during these phases the clitoris flows with blood, much like the penis, the breast swell and the vaginal lips
Examples of steroids include the dietary fat cholesterol, the sex hormones estradiol and testosterone, and the anti-inflammatory drug dexamethasone. Anabolic steroids mimic the effect of the natural androgen, testosterone. Testosterone naturally increases male characteristics which initially arise at puberty, including facial hair, body hair, muscle
