Perineal artery
Perineal artery
The Perineal artery (/pɛrɪˈniːl ˈɑːrtəri/; from Latin perineum, meaning "area around the anus and genitals") is a branch of the internal pudendal artery that supplies blood to the perineum and external genitals.
Anatomy
The perineal artery is a branch of the internal pudendal artery, which is itself 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. These branches include the posterior scrotal arteries in males and the posterior labial arteries in females.
Function
The primary function of the perineal artery is to supply blood to the perineum and external genitals. This includes the scrotum and penis in males, and the vulva and vagina in females. It also supplies blood to the muscles and skin of the perineum.
Clinical significance
Damage to the perineal artery can result in reduced blood flow to the perineum and external genitals, which can cause pain and potentially lead to tissue damage or necrosis. This can occur as a result of trauma, surgery, or certain medical conditions such as atherosclerosis.
