The seminal vesicle:
- A. is located above the prostate;
- B. is a pair organ;
- C. is located medially from the deferent ducts;
- D. has endocrine role, generating the seminal fluid;
Correct Answer: B
Rationale: The correct answer is B because the seminal vesicle is indeed a pair organ, meaning there are two of them in the male reproductive system. They are located posterior to the urinary bladder and are responsible for producing and secreting a significant portion of the seminal fluid.
Choice A is incorrect because the seminal vesicles are located behind the bladder, not above the prostate. Choice C is incorrect as the seminal vesicles are located laterally, not medially from the deferent ducts. Choice D is incorrect because the seminal vesicle is not an endocrine organ; it has an exocrine function in producing seminal fluid.

The female Bartholin glands correspond to the male _____.
- A. prostate
- B. Cowper's
- C. seminal vesicle
- D. glans
Correct Answer: B
Rationale: The female Bartholin glands are homologous to the male Cowper's glands. Both glands secrete fluid to lubricate the reproductive tract during sexual arousal. The prostate gland (choice A) is not the correct answer as it is a different structure that produces seminal fluid. The seminal vesicles (choice C) secrete a significant portion of the seminal fluid but are not the male counterpart to the Bartholin glands. The glans (choice D) refers to the tip of the penis and is not the correct counterpart to the Bartholin glands. Therefore, the correct answer is B, Cowper's glands.
The primary spermatocytes:
- A. are formed by spermatogonia mitosis;
- B. have a complete number of chromosomes;
- C. generate secondary spermatocytes;
- D. are diploid cells;
Correct Answer: D
Rationale: The correct answer is D because primary spermatocytes are diploid cells, containing a complete set of chromosomes (46 in humans). They are formed by spermatogonia through a process called meiosis. During meiosis, the primary spermatocytes undergo two divisions to generate haploid secondary spermatocytes with half the number of chromosomes. Choices A and C are incorrect because primary spermatocytes are formed by spermatogonia undergoing meiosis, not mitosis, and they generate secondary spermatocytes, not the other way around. Choice B is incorrect because primary spermatocytes are diploid, not haploid.
