Reproductive System Exam Questions Questions
Question 1 of 5
_______ is a lytic enzyme released by the sperm.
Correct Answer: A
Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.
Question 2 of 5
Which hormone is released from the testes?
Correct Answer: C
Rationale: The correct answer is testosterone. Testosterone is the primary male sex hormone produced in the testes. Progesterone is a female sex hormone primarily produced in the ovaries, not in the testes. Vasopressin is a hormone released by the pituitary gland to regulate water balance in the body, not produced by the testes. Therefore, choices A, B, and D are incorrect.
Question 3 of 5
Which of the following is an example of an oviparous animal?
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.
Question 4 of 5
Which space is present between the bladder and the uterus?
Correct Answer: A
Rationale: The correct answer is the vesico-uterine pouch. This space is specifically located between the bladder and the uterus. The pubovesical pouch is incorrect as it refers to the space between the pubic bone and the bladder. The retro-uterine pouch, also known as the pouch of Douglas, is located between the uterus and rectum. The recto-uterine pouch is not a recognized anatomical term, making it an incorrect choice.
Question 5 of 5
Which of the following hormone ratios is MOST likely to be increased in a patient with PCOS?
Correct Answer: B
Rationale: In patients with Polycystic Ovary Syndrome (PCOS), the LH/FSH ratio is most likely to be increased. This hormonal imbalance is a key characteristic of PCOS, where elevated LH levels relative to FSH contribute to the pathophysiology of the condition. Choice A, progesterone/estrogen ratio, is not typically a defining feature of PCOS. Choice C, FSH/LH ratio, is the reverse of what is commonly observed in PCOS. Choice D, glucagon/insulin ratio, is not directly related to the hormonal imbalances seen in PCOS.
