- Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.arrow_forwardFigure 18.12 Which of the following statements about the male reproductive system is false? a. The vas deferens carries sperm from the testes to the seminal vesicles. b. The ejaculatory duct joins the urethra. c. Both the prostate and the bulbourethral glands produce components of the semen. d. The prostate gland is located in the testes.arrow_forwardBesides producing gametes (sperm and eggs), the primary male and female reproductive organs also produce sex hormones. The _____ and the pituitary gland control secretion of both.arrow_forward

Select one: A. Estrogen causes accelerated development of the endometrium during the follicle stage and then maintains the thickness of the endometrium during the luteal stage. B. Progesterone causes the relatively slow development of the endometrium during the follicle stage and accelerates the thickening of the endometrium during the luteal stage. C. Estrogen causes the relatively fast thickening of the endometrium during the follicular stage. Progesterone maintains the thickness of the endometrium during the luteal phase. D. Estrogen causes the relatively slow development of the endometrium during the follicular stage. Progesterone causes accelerated thickening of the endometrium during the luteal phase.arrow_forward

(BOLDED WORDS ARE THE POSSIBLE ANSWERS IVE PROVIDED, WHIVCH ONE IS CORRECT FOR THE SENTENCE.)arrow_forwardSpermatogenesis usually occurs during the ___________ and continues in the _________ stage in some insects. The ________ is composed of germ cells and somatic mesodermal cells. Each follicle contains a large _________ that apparently serves as trophic function. The spermatogonia undergo several __________ divisions to form the primary spermatocytes. The primary spermatocytes become _________ in somatic cells.arrow_forwardAt the end of the uterine cycle, there is a significant drop in the level of LH, estrogen, and progesterone. This causes all of the following EXCEPT Select one: A. The maintenance of the corpus luteum to continue producing low levels of progesterone and estrogen. B.
