Which of the following tissues secrete proteolytic enzymes to liquefy semen?

Correct Answer: C

Rationale: The correct answer is C: prostate. The prostate gland secretes proteolytic enzymes such as prostate-specific antigen (PSA) to liquefy semen. This aids in sperm mobility and overall fertility. The other choices are incorrect because: A: bulbourethral gland secretes a clear fluid to lubricate the urethra during sexual arousal. B: urethra is a passageway for urine and semen but does not secrete proteolytic enzymes. D: testis produces sperm cells but does not secrete enzymes to liquefy semen.

Correct Answer: C

Rationale: The correct answer is C: cervicorrhaphy. "Cervico-" refers to the neck of the uterus, and "-rrhaphy" means suture. Therefore, cervicorrhaphy is the correct term for the procedure of suturing the neck of the uterus. A: Cervicography is a diagnostic imaging technique, not a procedure for suturing. B: Perineorrhaphy involves suturing the perineum, not the neck of the uterus. D: Cervicorrhexis refers to cutting or incising the neck of the uterus, not suturing it.

Correct Answer: C

Rationale: The correct answer is C because the straight tubules open into the rete testis, which is a network of tubules located at the hilum of the testis. This is where sperm produced in the seminiferous tubules are collected and transported to the epididymis for maturation. The other choices are incorrect because A is not accurate as straight tubules are not located inside the lobules, B is incorrect as straight tubules are a separate structure from the convoluted seminiferous tubules, and D is inaccurate as straight tubules do not open directly into the epididymal duct.

Correct Answer: A

Rationale: Step-by-step rationale: 1. The corpus spongiosum surrounds the urethra in the male external genital organ, aiding in the passage of urine and semen. 2. This structure is crucial for maintaining proper urinary and reproductive functions. 3. The other choices are incorrect because: - Choice B is vague and does not specifically relate to the male genital organ. - Choice C refers to the corpora cavernosa, which are erectile tissue in the penis, not the urethra. - Choice D describes the root of the penis but does not specifically relate to the corpus spongiosum.

Correct Answer: A

Rationale: The correct answer is A: ovary. The female reproductive system includes the ovaries, which are responsible for producing eggs and hormones like estrogen and progesterone. The Fallopian tubes are passageways for eggs to travel from the ovaries to the uterus, not a part of the system itself. The vagina is the birth canal and where sperm enters during intercourse, but it is not a reproductive organ. The vulva includes external genitalia like the labia and clitoris, but it is not a reproductive structure. Therefore, the ovary is the only structure directly involved in the reproductive process.
