1. 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.

2. What is the role of the prolactin hormone?

• A. Stimulates the development of milk-producing tissue.
• B. Stimulates milk storage.
• C. Stimulates milk production.
• D. Stimulates milk ejection.

Correct answer: C

Rationale: The correct answer is C: 'Stimulates milk production.' Prolactin hormone is responsible for promoting the production of milk in the mammary glands. This hormone does not directly stimulate the development of milk-producing tissue (Choice A), milk storage (Choice B), or milk ejection (Choice D). While these functions are related to lactation, the primary role of prolactin is to facilitate milk production.

3. _______ is a lytic enzyme released by the sperm.

• A. Hyaluronidase
• B. Trypsin
• C. Helicase
• D. None of the above

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.

4. Cryptorchidism is a condition where _________.

• A. One or both testes are not developed
• B. One or both testes fail to descend into the scrotum
• C. One or both testes are not formed
• D. None of the above

Correct answer: B

Rationale: Cryptorchidism is a condition where one or both testes fail to descend into the scrotum. This means that the testes do not properly move from the abdomen into the scrotum during fetal development. Choice A is incorrect because the issue is not about development but descent. Choice C is incorrect as it implies that the testes were never formed, which is not the case in cryptorchidism. Choice D is incorrect as cryptorchidism does involve the testes but rather their descent into the scrotum.

5. Laparoscopy uses a small instrument known as a laparoscope to:

• A. Take very detailed photographs
• B. Insert a hysteroscope for D&C
• C. Perform an abortion procedure
• D. Perform a hysterectomy

Correct answer: A

Rationale: Laparoscopy uses a small instrument known as a laparoscope to take very detailed photographs of the pelvic organs. This procedure is commonly used for diagnostic purposes, to visualize internal organs, and to perform minimally invasive surgeries. Choice B, inserting a hysteroscope for D&C, is incorrect as hysteroscopy is a different procedure used to examine the inside of the uterus, not the pelvic organs. Choice C, performing an abortion procedure, is incorrect as laparoscopy is not used for abortion. Choice D, performing a hysterectomy, is incorrect as although laparoscopy can be used in some cases for hysterectomy, its primary purpose is not for this procedure.
