MULTIPLE CHOICE
1. At the midpoint of the menstrual cycle, ovulation occurs in response to the
a. increase in progesterone.
b. increase in luteinizing hormone and FSH.
c. decrease in estrogen.
d. decrease in gonadotropin.
ANS: B
At the midpoint of the cycle, a burst of luteinizing hormone and a doubling of FSH secretion from the pituitary gland stimulate
ovulation. Ovulation does not occur in response to an increase in progesterone. An increase in estrogen causes the anterior pituitary
to release luteinizing hormone and FSH. Gonadotropin does not play a role in ovulation.
REF: Pg. 659
2. Ovulation occurs approximately how many days prior to the first day of menstruation?
a. 7
b. 10
c. 14
d. 21
ANS: C
Ovulation occurs approximately 14 days before the next cycle begins; thus, in a 28-day cycle, ovulation occurs about day14 of the
cycle. Ovulation does not occur 7 days after menstruation, on day 10 of the cycle, or 21 days into the menstrual cycle.
REF: Pgs. 658-659
3. During the first 2 weeks of the menstrual cycle, the endometrium proliferates under the influence of
a. estrogen.
b. testosterone.
c. progesterone.
d. hCG.
ANS: A
In the preovulatory phase, also called the proliferative phase, theca and granulosa cells in the developing follicles in the ovary
secrete estrogen. Testosterone is not secreted during the preovulatory phase. Progesterone is not related to the proliferation of the
endometrium. The endometrium is not proliferated by the presence of hCG.
REF: Pg. 659
4. The corpus luteum
a. is the site of implantation of a fertilized egg.
b. secretes hCG.
c. develops at the site of a ruptured ovarian follicle.
d. is part of the human placenta.
ANS: C
During the luteal phase the site of the ruptured follicle becomes a corpus luteum, which secretes estrogen and progesterone. The
corpus luteum degenerates if pregnancy does not occur. The corpus luteum does not secrete hCG. The corpus luteum is not a part of
the placenta.
REF: Pg. 660
5. The hormone released from the posterior pituitary gland during the milk ejection reflex is
a. gonadotropin.
b. prolactin.
c. vasopressin.
d. oxytocin.
ANS: D
Oxytocin is released from the posterior pituitary gland during lactation. Gonadotropin is not released during milk ejection. The
hormone prolactin is released from the anterior pituitary gland and helps stimulate milk production. Vasopressin is not related to
milk ejection.
