Which of the following is not a result of menopause?

Correct Answer: C

Rationale: The correct answer is C: increase in calcium deposition. Menopause is associated with a decrease in estrogen levels, leading to bone loss rather than an increase in calcium deposition. Loss of hormones (A) is a result of menopause due to the decline in estrogen and progesterone. Reduction in breast mass (B) occurs as estrogen levels decrease, impacting breast tissue. Psychological changes (D) such as mood swings and irritability are common during menopause due to hormonal fluctuations. Thus, an increase in calcium deposition is not a result of menopause, making choice C the correct answer.

Correct Answer: D

Rationale: The correct answer is D: Ductus epididymis. The straight tubules in the testis lead into the ductus epididymis because the sperm produced in the testis pass through the straight tubules and enter the epididymis for maturation and storage. This is a crucial step in the sperm development process before they are ready for ejaculation. Rationale: - A: Efferent ducts are incorrect because they connect the rete testis to the epididymis and are responsible for transporting sperm from the testis. - B: Afferent ducts are incorrect as they carry sperm from the rete testis to the epididymis. - C: Rete testis is incorrect as it is a network of tubules where the straight tubules converge and connect to the efferent ducts, not directly to the epididymis.

Correct Answer: B

Rationale: The correct answer is B: LH (Luteinizing Hormone) triggers ovulation. Firstly, LH surge stimulates the release of the mature egg from the ovary. Secondly, it plays a crucial role in the development of the corpus luteum, which produces progesterone to prepare the uterus for potential implantation. GnRH (Choice A) is the hormone that stimulates the release of LH and FSH (Choice C) from the pituitary gland, but it does not directly trigger ovulation. Estrogen (Choice D) is involved in the regulation of the menstrual cycle and prepares the uterine lining for implantation but does not directly trigger ovulation.

Correct Answer: B

Rationale: The correct answer is B: Estrogen. Granulosa cells are located in the ovarian follicles and are responsible for producing estrogen, a key female sex hormone. Estrogen plays a crucial role in the menstrual cycle, pregnancy, and development of secondary sexual characteristics. Progesterone is mainly produced by the corpus luteum, testosterone is primarily produced by the testes in males, and aldosterone is synthesized in the adrenal glands. Granulosa cells do not secrete these hormones, making choices A, C, and D incorrect.

Correct Answer: C

Rationale: The correct answer is C: Metrorrhea. Metrorrhea refers to the discharge of pus or mucus from the uterus. Dysmenorrhea (A) is severe menstrual pain, Hypomenorrhea (B) is abnormally light menstrual flow, and Oligomenorrhea (D) is infrequent or light menstrual periods. Therefore, based on the definition provided in the question, Metrorrhea is the correct term for the discharge of pus or mucus from the uterus.
