Spermatozoa cells, Sertoli cells: B) hypothalamus: C) Leydig cells: D) anterior pituitary gland. Prostate specific antigen (PSA) level test can determine the speediness of normal cancer signaling for generation of semen by the prostate, signaling for generation of mucous in the prostate, and signaling for generation of mucous by Leydig cells. 10) Based on what we know, the surgical removal of the seminal vesicles would likely cause sterility because PSA would not be produced. B) It would increase sterility because sperm would not be able to exit the body. C) It would likely reduce the volume of semen. D) It would enhance the fertilization potency of sperm in the uterus. E) It would cause the testes to migrate back into the abdominal cavity. H) The primary difference between estrous and menstrual cycles is that A) the endometrium shed by the uterus during the estrous cycle is reabsorbed, but the shed endometrium is excreted from the body during the menstrual cycle. B) Behavioral changes during estrous cycles are much less apparent than those of menstrual cycles. C) Season and climate have less pronounced effects on the estrous cycle than they do on menstrual cycles. D) Copulation normally occurs throughout the estrous cycle, whereas in menstrual cycles, copulation only occurs during the period surrounding ovulation. E) Most estrous cycles are of much longer duration compared to menstrual cycles. 12. Which is not associated with the uterine cycle? A) menstrual B) secretory C) spermatogenesis D) estrogen and progesterone 13) Ovulation is the follicular response to a burst of secretion of (choose the best answer) A) Luteinizing hormone B) progesterone C) inhibin D) prolactin E) estradiol. 14) The hypothalamic hormone that stimulates hormone secretion by the anterior pituitary gland is A) LH B) FSH C) inhibin D) GnRH E) estradiol. 15) Menopause is characterized by A) reduced synthesis of ovarian steroid hormones B) decline in production of the gonadotropin hormones by the adrenal gland C) cessation of the uterine endometrium menstrual cycle D) lack of blood supply to the ovaries. 16. Formation of human eggs usually takes place in the

Question 20 Which statement correctly describes the secretory phase of the uterine (menstrual) cycle? (3 points) a. Follicle stimulating hormone stimulates proliferation of the endometrium. b. During this phase, the endometrium detaches and sheds. c. Progesterone stimulates the endometrium to prepare for implantation. d. Decreased progesterone levels cause the endometrial cells to die. Question 21 Choose the correct statement related to the uterine (menstrual) cycle. (3 points) a. The menstrual phase of the cycle is from day 6 to day 14. b. During the secretory phase, progesterone levels are at their lowest levels. c. During the proliferative phase, progesterone levels rise. d. If fertilization occurs, the corpus luteum is maintained initially by progesterone. Question 22 Which statement about the female reproductive process is wrong? (3 points) a. Luteinizing hormone promotes formation of the corpus luteum. b. Ovulation usually occurs 14 days after the beginning of menses. c. Rebuilding the endometrium is under the control of estrogen. d. The monthly discharge of the uterus (menses) is initiated by increased levels of follicle-stimulating hormone and LH. Question 23 Which events in the monthly female reproductive cycle occur simultaneously? (3 points) a. Menstruation and the estrogen surge. b. Endometrial proliferation and development of the vesicular follicle. c. Degeneration of the corpus luteum and increased LH and FSH secretion. d. The secretory phase in the uterus and decreased progesterone levels.
Practice Multiple Choice: Which of the following structures does not produce one or more components of seminal fluid? Seminiferous tubules Seminal vesicles Urethra Prostate gland Answer: Explanation: In sperm, the head region is primarily associated with which of the following? [select all that are correct] Flagella Acrosome Nucleus Mitochondria Answer: Explanation: Which of the following is an event in the uterine cycle? [select all that are correct] Breakdown of the endometrium Thickening of the endometrium Ovulation Breakdown of the corpus luteum Answer: Explanation: Birth control pills containing progesterone are designed to block the normal progression of Implantation The ovarian cycle Spermatogenesis Fertilization Answer: Explanation: If, after childhood brain surgery, the anterior pituitary in a girl was unable to secrete hormones properly, at puberty what type of supplement(s) do you think would necessary? FSH and LH hCG GnRH Progesterone Answer: Explanation:
