Where does the prostatic part of the male urethra arise from?

• A. Prostate in the midline at proximal verumontanum level between the ejaculatory ducts
• B. Bladder neck
• C. Pelvic floor
• D. Verumontanum itself

Answer: (A)

The prostatic part is the segment of the urethra that runs through the prostate gland. It begins where the urethra enters the prostate from the bladder neck, so its start is within the gland itself. At this level, the urethra lies in the midline of the prostate and, on the posterior wall, the verumontanum marks a key landmark where the openings of the ejaculatory ducts are located. Therefore, the prostatic portion arises at the proximal verumontanum level, between the openings of the two ejaculatory ducts. The other options miss this central intraprostatic origin: the bladder neck is upstream, the pelvic floor isn’t the origin, and the verumontanum is a landmark within the prostatic urethra, not its starting point.
