Perineal artery

Perineal artery is a branch of the internal pudendal artery that supplies blood to the perineum. The perineum is the area between the anus and the genitals in both males and females.

Anatomy

The perineal artery is a branch of the internal pudendal artery, which is itself a branch of the internal iliac artery. The internal pudendal artery gives off several branches, including the perineal artery, before it enters the pudendal canal.

The perineal artery travels through the perineum, supplying blood to the structures in this area. It gives off several branches, including the posterior scrotal arteries in males and the posterior labial arteries in females.

Function

The main function of the perineal artery is to supply blood to the perineum. This includes the skin and muscles in this area, as well as the external genitalia. In males, this includes the scrotum and the base of the penis. In females, this includes the labia and the lower part of the vagina.

Clinical significance

Damage to the perineal artery can lead to a lack of blood supply to the perineum, which can cause tissue death and infection. This can occur as a result of trauma, surgery, or disease. Treatment typically involves restoring blood flow to the area, either through surgery or through the use of medications that improve blood flow.
