Urethra

This is an organ of reproduction and urination

It receives semen deposited from the ejaculatory into the prostatic urethra. This action is aided by peristalsis of the muscular wall of the ductus deferens. The last or secondary action follows the primary one through the agency of the bulbospongiosus. This allows semen to be deposited outside.

This is a channel that passes through the penis. It is surrounded by columnar epithelium and pseudostratified epithelium. It allows urine to pass through it. It is divided into the following parts

Male urethra

Female urethra:

Blood supply

Artery of bulb supplies the bulb of penis and the corpus spongiosum, together with the urethra. It is also supplied by vessels which supply the prostate gland such as the superior and inferior vesical arteries.  It is drained by the corresponding vein.

Nerve supply is via the perineal nerve.
