The prostate gland is located superior to which structure?

The prostate gland is located superior to which structure?

• A. Urinary bladder neck
• B. Seminal vesicles
• C. External urethral sphincter
• D. Ductus deferens

Answer: (C)

Understanding the spatial relationships in the male pelvic region helps answer this. The prostate sits just below the bladder neck and surrounds the prostatic urethra. The external urethral sphincter lies in the deep perineal pouch around the membranous portion of the urethra and is located below (inferior to) the prostate. So, the prostate is positioned superior to the external urethral sphincter. The other structures are located differently for context: the bladder neck is above the prostate, the seminal vesicles are posterior and superior to it, and the ductus deferens travels toward the prostate region rather than lying below it.
