Review (<br />

Figure (3,): Penile arterial supply cross section of the penis [Devine CJ Jr, Angermeier<br />

KW (1994) from, Campbell's urology update # 2004].<br />

After giving off a branch to the perineum. The three branches of the penile<br />

artery are the dorsal, the bulb urethral, and the cavernous arteries. The<br />

cavernous artery is responsible for tumescence of the corpus cavernosum<br />

and the dorsal artery for engorgement of the glans penis during erection. The<br />

bulbourethral artery supplies the bulb and corpus spongiosum. The<br />

cavernous artery enters the corpus cavernosum at the hilum of the penis,<br />
