- Figure 43.8 Which of the following statements about the male reproductive system is false? The vas deferens carries sperm from the testes to the penis. Sperm mature in seminiferous tubules in the testes. Both the prostate and the bulbourethral glands produce components of the semen. The prostate gland is located in the testes.The secretion of _____ controls the formation of sperm. a. testosterone b. LH c. FSH d. all of the aboveHow Is Sex Determined? The absence of a Y chromosome in an early embryo causes the: a. embryonic testis to become an ovary b. Wolffian duct system to develop c. Mllerian duct system to degenerate d. indifferent gonad to become an ovary e. indifferent gonad to become a testis
- Figure 43.17 Which of the following statements about the menstrual cycle is false? Progesterone levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. Menstruation occurs just after LH and FSH levels peak. Menstruation occurs after progesterone levels drop. Estrogen levels rise before ovulation, while progesterone levels rise after.Figure 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.Watch this video (http://openstaxcollege.org/l/spermpath) to explore the structures of the male reproductive system and the path of sperm that starts in the testes and ends as the sperm leave the penis through the urethra. Where are sperm deposited after they leave the ejaculatory duct?
- _____ production is continuous from puberty onward in males; _____ production is cyclic and intermittent in females. a. Egg; sperm b. Sperm; egg c. Testosterone; sperm d. Estrogen; eggA spermatogonial cell undergoes mitosis before entering the meiotic cell cycle en route to the production of sperm. However, during mitosis the cytoplasm fails to divide, and only one daughter cell is produced. A resultant sperm eventually fertilizes a normal ovum. What is the chromosomal complement of the embryo?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.
- Watch this video (http://openstaxcollege.org/l/ovulation) to observe ovulation and its initiation in response to the release of FSH and LH from the pituitary gland. What specialized structures help guide the oocyte from the ovary into the uterine tube?Figure 18.17 Which of the following statements about hormone regulation of the female reproductive cycle is false? a. LH and FSH are produced in the pituitary, and estrogen and progesterone are produced in the ovaries. b. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. c. Both progesterone and estrogen are produced by the follicles. d. Secretion of GnRH by the hypothalamus is inhibited by low levels of estrogen but stimulated by high levels of estrogen.Match each term with the most suitable description. ___epididymis a. conveys oocyte to uterus ___vas deferens b. can be inflated by blood ___vagina c. where sperm mature ___seminal vesicle d. target of vasectomy ___penis e. main contribution to semen ___oviduct f. sheds lining monthly ___uterus g. birth canal
