Reproductive Health Exam Questions And Answers
1. Which of the following is NOT a phase of the menstrual cycle?
- A. Follicular phase
- B. Ovulatory phase
- C. Luteal phase
- D. Secretory phase
Correct answer: D
Rationale: The secretory phase is not considered a distinct phase of the menstrual cycle; it is actually part of the luteal phase. During the luteal phase, the endometrium thickens due to progesterone secretion, preparing for implantation. The follicular phase is characterized by follicle development, leading to ovulation. The ovulatory phase is when the mature egg is released from the ovary. Therefore, the secretory phase is the correct answer as it is not a standalone phase but a part of the luteal phase.
2. How do contraceptive oral pills help in birth control?
- A. Preventing ovulation
- B. Killing ova
- C. Killing sperms
- D. More than one of the above
Correct answer: A
Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.
3. Where does the ovum receive the sperm?
- A. Animal pole
- B. Vegetal pole
- C. Zona pellucida
- D. None of the above
Correct answer: C
Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.
4. In which part of the fallopian tube is tubal abortion most common?
- A. Ampullary portion
- B. Isthmus
- C. Interstitial portion
- D. Infundibulum
Correct answer: C
Rationale: Tubal abortion is most common when the ovum implants in the interstitial portion of the fallopian tube. This location is the narrowest part of the tube, making it more prone to obstruction or difficulty in the passage of the fertilized ovum. Choices A, B, and D are incorrect because tubal abortion is more likely to occur in the interstitial portion rather than the ampullary portion, isthmus, or infundibulum of the fallopian tube.
5. 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.
