Final answer:
The prostate gland consists of glandular tissue, non-glandular tissue, and fibromuscular stromal tissue, which all contribute to the structure and function of the gland, particularly in the production of semen. The correct answer to the question is D. All of the above.
Step-by-step explanation:
The prostate gland is an essential part of the male reproductive system with a complex structure that contributes significantly to the composition of semen. This walnut-shaped gland surrounds the urethra, which is the tube connecting the urinary bladder to the external environment, and is responsible for producing a thin, alkaline, milky fluid that forms part of the semen.
Structurally, the prostate is composed of glandular tissue, non-glandular tissue, and fibromuscular stromal tissue. The glandular tissue is involved in the production of prostate fluid, which includes citrate, enzymes, and prostate specific antigen (PSA), a proteolytic enzyme that helps in semen liquefaction post-ejaculation. The non-glandular and fibromuscular stromal tissue provide a supportive framework and assist in the forceful expulsion of semen during ejaculation.
Therefore, the correct option that describes the components of the prostate gland is D. All of the above, which includes glandular tissue, non-glandular tissue, and fibromuscular stromal tissue.
