The dorsal arteries come from the internal pudendal arteries. This membrane covers the anterior part of pelvic outlet. It is pierced by the arteries of the erectile bodies and the dorsal arteries and nerves of the clitoris or penis. It arises from the abdominal aorta at the level of L2. Review the development and descent of the testis.
Testes begin as retroperitoneal structures in the posterior abdominal wall.
They are attached to the anterolateral abdominal wall by the gubernaculum. After the testes are in position in the scrotum, the gubernaculum persists as the scrotal ligament, while part of the processus vaginalis remains as a bursa-like sac called the tunica vaginalis testis. It occurs at the tail of the epididymis on the inferoposterior aspect of the testis. This artery is a branch of the internal pudendal artery. In females, the greater vestibular gland is the analogous structure, but it is not associated with the sphincter urethrae muscle.
