Reproductive Biology Worksheet

Which of the following structures acts as a "force field" preventing other sperm from fusing with the ova's membrane?

• zona corna

• zona glomerulosa

• zona pellucida

• corona radiata

Which of the following would be the result of a sudden major drop in progesterone production and release by the corpus luteum during the luteal phase?

• the uterine lining will grow, during this time, it cannot be shed

• the uterine lining will be maintained at low levels of progesterone and shed at higher levels of estrogen

• the uterine lining will cease to be maintained and will be shed (menstruation)

• the uterine lining will be maintained at low levels of estrogen and shed at higher levels of progesterone

What structure on the male spermatozoon contains hydrolytic enzymes critical for getting through to the ova's cell membrane?

• nucleus

• midpiece

• flagella

• acrosome

Which structure is labeled as the "central control" for the female reproductive system?

• vaginal canal

• ovaries

• uterus

• hypothalamus

Which of the following structures does not assist in the process of ovulation?

• cervix

• fimbriae

• uterine tubes

• ova and follicles

Which of the following structures of the male reproductive system does not have an analogous function and similar location in the female reproductive system?

• shaft

• corpus spongiosum

• glans head

• crus

Which of the following is not a function of the ovarian follicles?

• corpus luteum formation and continued production and release of progesterone

• produce follicular cells and granulosa to surround and protect ova

• produce and release FSH and LH to maintain ova and stimulate ovulation

• ejection of the oocyte and ovulation

Which of the following best describes the correct order for the ovarian cycle?

• Follicular phase: follicle maturation; ovulation; luteal phase: follicle degeneration – corpus luteum releases estrogen to maintain uterine lining; corpus albicans stops releasing estrogen and degenerates into corpus luteum

• Follicular phase: follicle maturation; ovulation; luteal phase: follicle degeneration – corpus luteum releases progesterone to maintain uterine lining; corpus albicans stops releasing progesterone and degenerates into corpus luteum

• Follicular phase: follicle maturation; ovulation; luteal phase: follicle degeneration – corpus luteum releases progesterone to maintain uterine lining; corpus albicans stops releasing estrogen and degenerates into corpus luteum

• Follicular phase: follicle degeneration; ovulation; luteal phase: follicle regeneration – corpus luteum releases estrogen to maintain uterine lining; corpus albicans stops releasing estrogen and degenerates into corpus luteum

The ____________________ responds to ovarian hormones and is shed during menstruation while the ________________ forms the new layer in preparation for housing an embryo and is unresponsive to ovarian hormones.

• The functional layer (stratum functionalis) responds to ovarian hormones and is shed during menstruation while the basal layer (stratum basalis) forms the new layer in preparation for housing an embryo and is unresponsive to ovarian hormones.

• The basal layer (stratum basalis) responds to ovarian hormones and is shed during menstruation while the functional layer (stratum functionalis) forms the new layer in preparation for housing an embryo and is unresponsive to ovarian hormones.

• The myometrium responds to ovarian hormones and is shed during menstruation while the endometrium forms the new layer in preparation for housing an embryo and is unresponsive to ovarian hormones.

• The perimetrium responds to ovarian hormones and is shed during menstruation while the myometrium forms the new layer in preparation for housing an embryo and is unresponsive to ovarian hormones.

Which of the following is not part of the menstrual cycle?

• vaginal canal

• uterus

• ovaries

• functional zone of endometrium
