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.
During the first trimester, hCG produced from the chorion maintains the corpus luteum. What is the purpose of maintaining the corpus luteum?
Select one:
a. The corpus luteum produces relaxin, which thickens the endometrium.
b. The corpus luteum ensures that the endometrium does not break down during the first trimester.
c. The corpus luteum supports the formation of the placenta.
d. The chorion forms the fetal part of the placenta, and the corpus luteum supports the maternal part of the placenta.
How do tubal ligations and vasectomies prevent further pregnancies?
Select one:
a. The corpus luteum and the epididymis are suppressed using a chemical swab. The fertilized egg could no longer implant in the endometrium.
b. The Fallopian tubes and vas deferens are cut and tied off, thereby preventing the movement of the eggs and sperm.
c. The Fallopian tubes and the vas deferens are cut. Eggs and sperm can no longer be produced.
d. The Fallopian tube and vas deferens are cut and tied off, thereby reducing needed reproductive hormone levels.
