Question

1. semen is composed of spermatozoa and secretions from which of the following?

a. prostate gland only
b. seminal vesicles only
c. prostate gland, seminal vesicles, and bulbourethral glands
d. seminal vesicles and bulbourethral glands

Explanation:

Semen is a mixture. Spermatzoa (sperm cells) are produced in the testes. The seminal vesicles contribute a significant portion of the fluid (e.g., fructose for energy). The prostate gland adds a milky - white fluid that has enzymes and other substances. The bulbourethral glands secrete a clear, viscous fluid that helps in lubrication and neutralizing acidity in the urethra. So semen is composed of spermatozoa and secretions from all three glands (prostate gland, seminal vesicles, and bulbourethral glands).

Answer:

C. Prostate gland, seminal vesicles, and bulbourethral glands
