1. 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.

2. What is an organelle that helps the sperm to penetrate the ovum?

• A. Acrosome
• B. Zona pellucida
• C. Megalis
• D. None of the above

Correct answer: A

Rationale: The correct answer is Acrosome. The acrosome is an organelle located at the head of a sperm cell and contains enzymes that aid in the penetration of the ovum during fertilization. The Zona pellucida is a glycoprotein membrane surrounding the ovum, not an organelle. Megalis is not a relevant organelle in this context. Therefore, the correct choice is A, Acrosome.

3. The following are delays associated with maternal mortality EXCEPT:

• A. Delay in recognizing danger signs
• B. Delay in arrival at a health facility
• C. Delay in initiating treatment
• D. Excessive blood loss

Correct answer: D

Rationale: The correct answer is D. Excessive blood loss is not a delay associated with maternal mortality but rather a direct complication. Delays in recognizing danger signs, arriving at a health facility, and initiating treatment are factors that can contribute to maternal mortality by impeding timely access to necessary care.

4. The endometrium is shed up to the basal layer during this phase of the menstrual cycle:

• A. Ovulation
• B. Regenerative
• C. Secretory
• D. Menstruation

Correct answer: D

Rationale: The correct answer is D. During the menstrual phase of the menstrual cycle, the endometrium is shed up to the basal layer. This shedding occurs as a result of decreased levels of estrogen and progesterone, leading to the breakdown and subsequent shedding of the endometrial lining. Choice A, ovulation, is incorrect as ovulation is the release of an egg from the ovary, which occurs during the mid-cycle. Choice B, regenerative, is incorrect as it does not specifically refer to the phase where the shedding of the endometrium occurs. Choice C, secretory, is incorrect as it refers to the phase where the endometrium thickens in preparation for possible implantation of a fertilized egg, not shedding.

5. Which of the following hormones promotes endometrial growth?

• A. LH
• B. FSH
• C. Estrogen
• D. Progesterone

Correct answer: C

Rationale: Estrogen is the hormone responsible for promoting endometrial growth. Estrogen helps thicken the endometrium during the menstrual cycle in preparation for implantation. LH (Choice A) and FSH (Choice B) are involved in regulating the menstrual cycle but do not directly promote endometrial growth. Progesterone (Choice D) is important for maintaining the endometrium after ovulation but is not the primary hormone responsible for promoting its growth.
