Wolffian duct is also known as ____________.

Correct Answer: A

Rationale: The correct answer is A: Mesonephric duct. The Wolffian duct is also known as the mesonephric duct because it develops in the embryo to form the male reproductive system. It gives rise to various structures such as the epididymis, vas deferens, and seminal vesicles. The other choices are incorrect because the ejaculatory duct is formed by the union of the vas deferens and seminal vesicle, the major sublingual duct is associated with saliva production, and the cystic duct is part of the biliary system and not related to the male reproductive system.

Correct Answer: C

Rationale: The correct answer is C: Proliferative phase. During this phase, estrogen levels increase, stimulating the endometrium to thicken and proliferate. This prepares the uterus for potential implantation of a fertilized egg. The other choices are incorrect because: A: Menstrual phase is when the endometrium sheds, not thickens. B: Preovulatory phase is characterized by the maturation of the ovarian follicles, not endometrial thickening. D: Follicular phase is synonymous with the preovulatory phase and focuses on ovarian follicle development, not endometrial thickening.

Correct Answer: A

Rationale: Rationale: 1. Inhibin is produced by the ovaries and testes in response to FSH stimulation. 2. Inhibin acts as a negative feedback signal to inhibit further FSH release. 3. This mechanism helps regulate the levels of FSH in the body. Summary: - Relaxin is a hormone involved in pregnancy and does not directly inhibit FSH release. - GnRH stimulates FSH release rather than inhibiting it. - hCG is produced during pregnancy and does not have a direct role in inhibiting FSH secretion.

Correct Answer: B

Rationale: The correct answer is B: Body. Corpus commonly refers to a collection of written or spoken texts, which together form a body of work. "Body" is the best choice as it encompasses the idea of a collection or group of related items. A is incorrect as it refers specifically to the abdomen, not the general term. C, Death, and D, Head, are unrelated to the general meaning of "corpus" as they do not convey the idea of a body or collection.

Correct Answer: D

Rationale: The correct answer is D (Both a & c) because benign tumors originating in the myometrium are typically either fibroids (choice A) or leiomyomas (choice C), which are essentially the same thing. Fibroids and leiomyomas are both non-cancerous growths arising from smooth muscle cells in the myometrium. Rhabdomyoma (choice B) is a benign tumor arising from striated muscle cells, not smooth muscle cells like fibroids and leiomyomas. So, choices A, B, and C are incorrect because only fibroids and leiomyomas specifically originate in the myometrium.
