Textbook Question
Chapter 26, Problem 19CYR
Mark the following statements about the uterine cycle as true or false. If a statement is false, correct it to make a true statement.
a. During the proliferative phase, the endometrium prepares for the implantation of the conceptus by enlarging the endometrial glands and secreting glycogen into the uterine cavity.
b. During the secretory phase, the endometrium generates a new stratum functionalis.
c. During the menstrual phase, the uterus sheds the stratum basalis of the endometrium, which results in the discharge of blood and tissue from the vagina.

At 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. The start of menstruation, which breaks down the blood vessels and tissues formed during the follicular stage.
C. Negative feedback loop to the pituitary to secrete more FSH and LH.
D. An increase in smooth muscle contractions of the uterus.
