Primary spermatogonium undergo:
- A. two mitotic divisions to become a secondary spermatocyte
- B. mitosis and then meiosis to become a secondary spermatocyte
- C. two meiotic divisions to become a secondary spermatocyte
- D. meiosis and differentiation to become a secondary spermatocyte
Correct Answer: B
Rationale: The correct answer is B. Primary spermatogonium undergo mitosis to replicate and maintain the diploid chromosome number, then meiosis to reduce the chromosome number, resulting in secondary spermatocytes. Choice A is incorrect as it skips meiosis. Choice C is incorrect as it suggests two meiotic divisions from primary spermatogonium, which is not accurate. Choice D is incorrect because it fails to mention the initial step of mitosis before meiosis in the process.

Which ligament arises from the pubic symphysis in males?
- A. Fundiform ligament
- B. Broad ligament
- C. Suspensory ligament
- D. Ejaculatory ligament
Correct Answer: C
Rationale: The correct answer is C: Suspensory ligament. This ligament arises from the pubic symphysis in males and supports the male reproductive organs.

The inner mucosal layer of the uterus that is sloughed off approximately every 28 days is called the ________.
- A. endometrium
- B. myometrium
- C. perimetrium
- D. epimetrium
Correct Answer: A
Rationale: The correct answer is A: endometrium. The endometrium is the inner mucosal layer of the uterus that sheds during menstruation. It is where implantation of a fertilized egg occurs. Myometrium (B) is the middle muscular layer, responsible for uterine contractions. Perimetrium (C) is the outer layer of the uterus. Epimetrium (D) is not a recognized term in anatomy.
The outer serosal layer of the uterus is the _____.
- A. perimetrium
- B. cervix
- C. endometrium
- D. myometrium
Correct Answer: A
Rationale: The correct answer is A: perimetrium. The perimetrium is the outer serosal layer of the uterus, providing protection and support. The other choices are incorrect: B. cervix is the lower portion of the uterus, C. endometrium is the inner lining where implantation occurs, and D. myometrium is the middle muscular layer of the uterus. The perimetrium is the outermost layer, making it the correct choice.
The female genitive ducts include the following structures:
- A. uterus;
- B. vulva;
- C. vagina;
- D. ovary
Correct Answer: D
Rationale: The correct answer is D: ovary. The female genitive ducts refer to the structures involved in the production, transport, and release of eggs. The ovary is the primary organ responsible for producing eggs. The uterus, vulva, and vagina are not directly involved in egg production but rather in the reception, nurturing, and passage of the egg. Therefore, the ovary is the correct choice as it is a key structure in the female reproductive system responsible for egg production.
