FSH levels are highest during the

Question 1.
FSH levels are highest during the

Select one:
a. follicular stage;  at 7 to 12 days
b. luteal stage;  at 16 to 21 days
c. luteal stage;  at 21 to 28 days
d. follicular stage;  at 0 to 7 days


Question 2.
FSH causes the ovary initially to secrete

Select one:
a. estrogen during the follicular stage
b. estrogen during the luteal stage
c. progesterone during the follicular stage
d. progesterone during the luteal stage




Please use the graphs on page 500.


Question 3
The significance of FSH regulating estrogen secretion by the ovary is to

Select one:
a. initiate the building of the endometrium during the follicular stage
b. initiate the building of the endometrium during the luteal stage
c. cause the shedding of the endometrium during the follicular stage
d. cause the shedding of the endometrium during the luteal stage


Question 5
Luteinizing hormone (LH) secreted by the anterior pituitary gland influences a follicle to rupture releasing its ovum and promotes the
Select one:
a. development of the corpus luteum and the secretion of progesterone
b. disintegration of the corpus luteum and the inhibition of progesterone secretion
c. development of the follicle and the secretion of estrogen
d. disintegration of the follicle and the inhibition of estrogen secretion


Question 6
LH influences the corpus luteum to secrete progesterone, which peaks during the

Select one:
a. luteal stage at day 21
b. follicular stage at day 21
c. luteal stage at day 12
d. follicular stage at day 12




Question 7
Progesterone levels are high during the luteal stage to

Select one:
a. maintain the uterus lining and calm uterus smooth muscle contraction
b. maintain the uterus lining and increase uterus smooth muscle contractions
c. cause a breakdown of the uterus lining and menstrual contractions begins
d. cause a breakdown of the uterus lining and menopause begins


Please use the graphs on page 500.

Question 8
A decline of LH, estrogen, and progesterone at day 28 causes all the following except
Select one:
a. a breakdown of the blood vessels and tissues formed in the follicular stage and the start of menstrual flow
b. an increase in smooth muscle contractions of the uterus
c. a negative feedback loop to the pituitary to inhibit further FSH and LH secretion
d. a negative feedback loop to the pituitary to start a new ovarian and uterine cycle


 Human reproductive systems are regulated through negative and positive feedback loops. The correct operation of a feedback mechanism linked with a hormone is

Select one:
a. FSH secretion → positive feedback to ovaries; estrogen secretion → positive feedback to the pituitary
b. LH secretion → positive feedback to ovaries: estrogen secretion → negative feedback to the pituitary
c. LH secretion → negative feedback to testes; testosterone → positive feedback to the pituitary
d. FSH secretion → negative feedback to testes;  testosterone secretion → negative feedback to the pituitary
