Reproductive System Exam Questions
1. Where does fertilization normally occur?
- A. Ampulla
- B. Interstitial portion
- C. Isthmus
- D. Infundibulum
Correct answer: A
Rationale: Fertilization typically occurs in the ampulla of the fallopian tube. The ampulla provides the ideal environment for fertilization due to the presence of cilia that help transport the egg and sperm, as well as the nourishing fluid within this region. The interstitial portion, isthmus, and infundibulum of the fallopian tube are not the primary sites for fertilization. The interstitial portion connects the fallopian tube to the uterine cavity, the isthmus is the narrowest part near the uterus, and the infundibulum is the funnel-shaped end near the ovary, where the egg is captured after ovulation.
2. Which of the following is an example of a viviparous animal?
- A. Goat
- B. Duck
- C. Crocodile
- D. None of the above
Correct answer: A
Rationale: The correct answer is A, goat. Viviparous animals give birth to live young ones instead of laying eggs. Ducks and crocodiles are oviparous, meaning they lay eggs, making them incorrect choices. 'None of the above' is incorrect because goats are a valid example of viviparous animals.
3. What is the content of the acrosome?
- A. Lipids
- B. Hormones
- C. Digestive enzymes
- D. None of the above
Correct answer: C
Rationale: The correct answer is C: Digestive enzymes. The acrosome is a structure found in sperm cells that contains enzymes used to penetrate the egg during fertilization. Choice A (Lipids) and Choice B (Hormones) are incorrect as the primary content of the acrosome is digestive enzymes, not lipids or hormones. Choice D (None of the above) is incorrect as the acrosome does contain a specific substance, which are digestive enzymes.
4. Which of the following is not a characteristic of an ideal contraceptive?
- A. Irreversible
- B. Easily available
- C. User-friendly
- D. Effective with least side effects
Correct answer: A
Rationale: The correct answer is A: 'Irreversible.' An ideal contraceptive should not be irreversible because it should allow individuals to have the option to discontinue its use if desired. Choices B, C, and D are characteristics of an ideal contraceptive. Contraceptives should be easily available to ensure widespread accessibility, user-friendly to promote proper and consistent use, and effective with minimal side effects to maximize safety and tolerability.
5. Which of the following is an example of an oviparous animal?
- A. Pigeon
- B. Elephant
- C. Sheep
- D. None of the above
Correct answer: A
Rationale: The correct answer is A: Pigeon. Oviparous animals are those that lay eggs, and pigeons fall under this category. Choice B, Elephant, is incorrect because elephants are viviparous, giving birth to live young. Choice C, Sheep, is also incorrect as sheep are viviparous animals. Choice D, None of the above, is not the correct answer as a pigeon is indeed an example of an oviparous animal.
