Arteria perinealis

Arteria Perinealis is a small artery that branches off from the internal pudendal artery. It is part of the human circulatory system and plays a crucial role in supplying blood to the perineum and external genitals.

Anatomy

The Arteria Perinealis originates from the internal pudendal artery, which is a branch of the internal iliac artery. It travels through the pudendal canal and gives off several branches to supply the perineum and external genitals.

Function

The primary function of the Arteria Perinealis is to supply oxygenated blood to the perineum and external genitals. This includes the scrotum in males and the labia majora in females. It also supplies blood to the anal sphincter and surrounding tissues.

Clinical Significance

Damage or blockage of the Arteria Perinealis can lead to serious health issues. This can result from trauma, surgery, or diseases such as atherosclerosis. Symptoms can include pain, swelling, and tissue death in the perineum and external genitals. Treatment typically involves surgery to repair or bypass the damaged artery.
