pudendaartären

The pudendal artery is a major blood vessel within the pelvic region. It originates from the internal iliac artery, which is a large branch of the abdominal aorta. The pudendal artery then travels inferiorly and anteriorly through the pelvis, passing through the greater sciatic foramen and then re-entering the pelvis by passing through the lesser sciatic foramen.

As it courses through the pelvis, the pudendal artery gives off several important branches. These branches supply blood to a variety of structures. Key branches include the inferior rectal arteries, which supply the anal canal and rectum; the perineal artery, which supplies the muscles and skin of the perineum, including the scrotum in males and the labia majora in females; and the dorsal artery of the penis or clitoris, which supplies the erectile tissues of these organs.

The pudendal artery plays a crucial role in the vascularization of the external genitalia and the distal portions of the rectum and anus. Its branches are essential for the function of these structures, including sexual arousal and defecation. Due to its location and the structures it supplies, the pudendal artery is a significant consideration in pelvic surgery and in the management of injuries to the pelvic region. Understanding its anatomy and branching pattern is important for medical professionals.
