internal pudendal artery
The internal pudendal artery is an artery that branches off the internal iliac artery, providing blood to the external genitalia.
The internal pudendal artery is the terminal branch of the anterior trunk of the internal iliac artery. It is smaller in the female than in the male.
==Path==
It exits the pelvic cavity through the greater sciatic foramen, inferior to the piriformis muscle, to enter the gluteal region.
It then curves around the sacrospinous ligament to enter the perineum through the lesser sciatic foramen.
It travels through the pudendal canal with the internal pudendal veins and the pudendal nerve.
