Which of the following is NOT a vessel or structure of the penis?

• A. Deep artery of the penis
• B. Dorsal artery of the penis
• C. Corpus spongiosum
• D. Inferior vesicle artery

Answer: (D)

The inferior vesicle artery is not a vessel or structure of the penis. This artery primarily supplies blood to the bladder and other structures in the pelvic region, particularly in males. Its role is associated with the vascular supply to urogenital organs rather than directly contributing to the anatomy or function of the penis. In contrast, the deep artery of the penis and the dorsal artery of the penis are both critical components of penile vascular anatomy. The deep artery supplies blood to the erectile tissue, while the dorsal artery irrigates the skin and tissue on the top surface of the penis. The corpus spongiosum is a key anatomical structure of the penis itself, surrounding the urethra and playing a role in maintaining the urethral patency during erection and ejaculation. Thus, identifying the inferior vesicle artery as the correct response highlights the distinction between structures specific to the penis and those serving other pelvic organs.
