Textbook Question
Chapter 28, Problem 12RQ
What would happen if the trophoblast did not secrete hCG upon implantation of the blastocyst?
- Tire cells would not continue to divide.
- Tire corpus luteum would continue to produce progesterone and estrogen.
- Menses would flush the blastocyst out of the uterus.
- Tire uterine mucosa would not envelop the blastocyst.

Clomiphene Citrate is a fertility drug that stimulates hypothalamic secretion of Gonadotropin releasing Hormone (GnRH) in females and induces ovulation. Explain how increased GnRH with Clomiphene Citrate treatment would affect follicle maturation and ovulation in women (explain how increased GnRH would affect FSH, LH, Estrogen, and ovulation).
What is the outer layer (outer cell mass) of the blastocyst termed
Trophoblast
O Embryoblast
Epiblast
Hypoblast
Which of the following statements does NOT correctly describe the events following fertilization?
Select one:
a. Only the inner cell mass cells in a blastocyst are pluripotent.
b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding.
c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican.
d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body.
