Which branch of the autonomic nervous system is responsible for penile erection? Ejaculation?
Step by step
Solved in 2 steps
- How does Viagra help with erectile dysfunction? Which part of the autonomic NS control emission and ejaculation?What is the corpus luteum? Assuming the ovum remains unfertilized, what is the lifespan of the corpus luteum? What is the corpus albicans?Shedding of the functional layer of the endometrium also known as menstruation occurs when a) the concentration of LH in the blood peaks b ) the corpus luteum degenerates and turns into corpus albican c ) blood level of progesterone from the corpus luteum increases e ) blood level of FSH falls off
- What naturally occurring event could rescue the corpus luteum and prevent its degeneration starting in the middle of the luteal phase?Which of the following functions are the cremaster muscles involved in? a ) responsible for penile erection . b) contract to push sperm along the vas deferens c ) regulate the temperature of the testes . e ) they contract to allow ejaculation .Name two structures that are homologous between the male and female reproductive systems. Name the hormones produced by follicle cells and the corpus luteum.
- What causes an erection in the male penis? a) Dilation (opening) of the smooth muscles around the veins leaving the penis and constriction of the smooth muscles around the arteries entering the penis creates engorgement of spongy tissue in the penis with blood. O b) Dilation (opening) of the smooth muscles around the arteries entering the penis and constriction (closing) of the smooth muscles around the veins leaving the penis creates engorgement of spongy tissue in the penis with blood. c) Muscle contractions of the testes d) Muscle contractions along the urethraIf the ovum is not fertilized, the corpus luteum regresses, and the endometrium sloughs off to result in the first day of menstrual bleeding. The latter event would be duplicated, even if fertilization occurred, if receptors for which of the following hormones were occupied by an antagonist? A) Dehydroepiandrosterone B) Estradiol C ) Estriol D) Estrone E) ProgesteroneSexual arousal results in a generally positive sympathetic response, e.g. increased heart rate, increased breathing rate and depth, etc. How is it, then, that erection can occur if sympathetic activity causes vasoconstriction and prevents blood flow into the vascular spaces of the penis?
