Which of the following statements relating to testosterone is correct?
- A. testosterone levels rise and fall every month
- B. testosterone levels rise after puberty and slow decline throughout a male's life.
- C. testosterone levels are at their highest during gestation.
- D. testosterone levels are at their highest level just after birth.
Correct Answer: B
Rationale: The correct answer is B because testosterone levels do rise after puberty and slowly decline throughout a male's life due to aging. This is because testosterone plays a crucial role in male development during puberty and is responsible for maintaining male characteristics. The other choices are incorrect as testosterone levels do not rise and fall every month (A), are not at their highest during gestation (C), and are not at their highest just after birth (D).

During the 12-hr period preceding ovulation, which of the following is true?
- A. The plasma concentration of estrogen is rising
- B. A surge of luteinizing hormone is secreted from the pituitary
- C. The surge occurs immediately after the formation of the corpus luteum
- D. The surge followed immediately by a fall in the plasma concentration of progesterone
Correct Answer: B
Rationale: The correct answer is B because a surge of luteinizing hormone (LH) is necessary for ovulation to occur, typically happening 24-36 hours before ovulation. This surge triggers the release of the mature egg from the ovarian follicle. Choices A, C, and D are incorrect as estrogen levels peak just before ovulation, the corpus luteum forms after ovulation, and progesterone levels rise after ovulation, not fall immediately after the LH surge.

The corpus luteum secretes whereas oogenesis will produce ___
- A. FSH. ova/ ovum.
- B. LH.
- C. 2; 2
- D. prolactin.
Correct Answer: A
Rationale: The correct answer is A because the corpus luteum secretes progesterone, not FSH. Oogenesis produces ova/ovum, not FSH, LH, or prolactin. FSH and LH are hormones produced by the pituitary gland to regulate the menstrual cycle, not by the corpus luteum or involved in ova production. Prolactin is a hormone involved in milk production, not in oogenesis or corpus luteum function. Therefore, A is correct as it correctly identifies the function of the corpus luteum and the product of oogenesis.
Arterial supply of breast include
- A. Internal thoracic artery
- B. Thoracoaromial artery
- C. Superior epigastric artery
- D. Common carotid artery
Correct Answer: A
Rationale: The correct answer is A: Internal thoracic artery. The internal thoracic artery is a major branch of the subclavian artery and supplies the breast tissue. It gives rise to the perforating branches that supply the breast. The other choices, B, C, and D, are incorrect because the thoracoaromial artery primarily supplies the upper limb, the superior epigastric artery supplies the anterior abdominal wall, and the common carotid artery supplies the head and neck, but not the breast tissue. Therefore, based on the anatomical knowledge of arterial supply, the internal thoracic artery is the correct choice for the arterial supply of the breast.
