Anatomical terminology

The inferior rectal artery (inferior hemorrhoidal artery) is an artery that supplies blood to the anal canal and the perineum. It is a branch of the internal pudendal artery.

Anatomy

The inferior rectal artery arises from the internal pudendal artery, which is a branch of the internal iliac artery. It travels through the ischioanal fossa and supplies the lower part of the rectum, the anal canal, and the surrounding skin of the perineum.

Function

The primary function of the inferior rectal artery is to provide oxygenated blood to the tissues of the anal canal and the perineum. This is crucial for maintaining the health and function of these areas, which are involved in the excretion of waste and other bodily functions.

Clinical significance

Damage or obstruction of the inferior rectal artery can lead to complications such as ischemia or hemorrhoids. Proper blood flow through this artery is essential for the health of the anal canal and surrounding tissues.
