The placenta is developed from which part of the trophoblast?
- A. Chorionic Frondosum
- B. Anchoring Villi
- C. Chorionic Laeve
- D. Body Stalk
Correct Answer: A
Rationale: The correct answer is A: Chorionic Frondosum. The placenta is developed from the chorionic frondosum part of the trophoblast. This structure gives rise to the fetal part of the placenta. Choices B, C, and D are incorrect. Anchoring Villi are projections from the chorionic plate that attach the placenta to the uterine wall. Chorionic Laeve refers to the smooth chorion that covers the fetal surface of the placenta. The Body Stalk is a structure that connects the early embryo to the trophoblastic pole of the blastocyst.

- A. Regenerative
- B. Menstruation
- C. Ovulation

- B. The corpus luteum produces progesterone to maintain the endometrium.
- C. The corpus luteum produces testosterone to inhibit ovulation.

Choice C is incorrect as testosterone is produced in smaller amounts by the ovaries and adrenal glands but does not play a significant role in maintaining the endometrium. Choice D is incorrect as the corpus luteum plays a crucial role in producing progesterone to support the endometrium.
