1. What does Bidder's canal receive?

• A. Eggs
• B. Sperms
• C. Ammonia
• D. Oxygenated blood

Correct answer: B

Rationale: Bidder's canal is a part of the male reproductive system and receives sperm from the testes. The other choices are incorrect because Bidder's canal is not associated with receiving eggs, ammonia, or oxygenated blood.

2. Which of the following is used to differentiate abdominal mass from pelvic mass on clinical examination?

• A. Size
• B. Site
• C. Margins
• D. Lower border

Correct answer: D

Rationale: The lower border is used to differentiate between an abdominal mass and a pelvic mass during clinical examination. The lower border of the mass provides important information about its location and origin. The size (Choice A) alone may not always clearly distinguish between abdominal and pelvic masses. The site (Choice B) and margins (Choice C) are also important factors, but they are not as specific in differentiating between abdominal and pelvic masses as the lower border.

3. Which hormone regulates the production of milk after childbirth?

• A. Prolactin
• B. Oxytocin
• C. Estrogen
• D. Progesterone

Correct answer: A

Rationale: The correct answer is Prolactin. Prolactin is the hormone responsible for regulating the production of milk after childbirth. It stimulates the mammary glands in the breasts to produce milk. Oxytocin, on the other hand, is responsible for the ejection of milk from the breasts. Estrogen and progesterone play roles in the menstrual cycle and pregnancy but are not directly involved in milk production. Therefore, choices B, C, and D are incorrect.

4. What is one role of the hormone estrogen?

• A. Stimulates the development of the milk-producing tissue.
• B. Stimulates the production of lactoferrin.
• C. Stimulates the development of the nipple and duct system in the breast.
• D. Stimulates the secretion of relaxin.

Correct answer: A

Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.

5. Which hormone is primarily responsible for the development of female secondary sexual characteristics?

• A. Progesterone
• B. Testosterone
• C. Estrogen
• D. Oxytocin

Correct answer: C

Rationale: Estrogen is primarily responsible for the development of female secondary sexual characteristics. Progesterone, while important in the menstrual cycle and pregnancy, is not primarily responsible for secondary sexual characteristics. Testosterone is the primary male sex hormone. Oxytocin is involved in labor, lactation, and social bonding, but not in the development of female secondary sexual characteristics.
