Reproductive System Exam Questions
1. Which of the following is not a barrier method of birth control?
- A. Vaults
- B. Diaphragms
- C. Sterilization
- D. Cervical caps
Correct answer: C
Rationale: The correct answer is C, Sterilization. Sterilization is a permanent form of birth control that involves surgical procedures to prevent pregnancy by blocking the fallopian tubes or vas deferens. Barrier methods physically prevent sperm from reaching the egg, such as vaults, diaphragms, and cervical caps. These devices create a barrier to sperm, unlike sterilization. Therefore, choices A, B, and D are all considered barrier methods of birth control.
2. Which hormone is detected in pregnancy tests?
- A. Estrogen
- B. Progesterone
- C. Luteinizing hormone (LH)
- D. Human chorionic gonadotropin (hCG)
Correct answer: D
Rationale: Human chorionic gonadotropin (hCG) is the hormone detected in pregnancy tests. During pregnancy, the placenta produces hCG, which can be detected in the urine or blood to confirm pregnancy. Estrogen and progesterone are also essential hormones in pregnancy but are not typically used for pregnancy tests. Luteinizing hormone (LH) is involved in the menstrual cycle and ovulation, not pregnancy.
3. Approximately how many primordial follicles are present in the cortex of the ovary at birth?
- A. 250,000
- B. 200,000
- C. 150,000
- D. 100,000
Correct answer: A
Rationale: The correct answer is A: 250,000. At birth, there are approximately 250,000 primordial follicles in the cortex of each ovary. These primordial follicles represent the reserve of oocytes that a female will have throughout her reproductive life. Choice B, 200,000, is incorrect as the number is higher. Choices C and D, 150,000 and 100,000 respectively, are also incorrect as they underestimate the actual number of primordial follicles present at birth.
4. What does MTP stand for?
- A. Medical Termination of Parturition
- B. Mechanical Transfer of Pollen
- C. Medical Termination of Pregnancy
- D. Maternally Transmitted Pathogens
Correct answer: C
Rationale: The correct expansion for MTP is Medical Termination of Pregnancy. This term is commonly used in healthcare to refer to the procedure of ending a pregnancy. Choices A, B, and D are incorrect because they do not accurately represent the expansion of the abbreviation MTP. Choice A refers to labor induction, choice B is related to plant reproduction, and choice D deals with the transmission of pathogens from mother to offspring.
5. What is the role of relaxin hormone?
- A. Relaxation of the symphysis pubis.
- B. Stimulation of milk production.
- C. Stimulating the development of the nipple and duct system in the breast.
- D. None of the above.
Correct answer: A
Rationale: The correct answer is A: Relaxation of the symphysis pubis. Relaxin hormone is responsible for loosening the ligaments in the pelvic area, particularly the symphysis pubis, to prepare for childbirth. Choice B, stimulation of milk production, is incorrect as this is primarily regulated by prolactin. Choice C, stimulating the development of the nipple and duct system in the breast, is incorrect as this is mainly influenced by estrogen and progesterone during pregnancy. Therefore, the correct role of relaxin hormone is the relaxation of the symphysis pubis.
