- Perineal branch of internal pudendal artery
- Superficial perineal artery
The perineal artery arises from the internal pudendal artery and supplies some of the perineal musculature and external genitalia.
Summary
- Origin: branches off the internal pudendal artery, arising at the level of the posterior angle of the perineal membrane
-
Branches: it has two branches:
- a transverse perineal branch
- a terminal posterior scrotal (male) or labial (female) artery 1
-
Course: pierces the perineal membrane at its origin, traveling in the superficial perineal pouch to reach the scrotum or labia
- notably, the perineal artery courses between the bulbospongiosus and ischiocavernosus muscles
- the transverse perineal branch arises at the level of the transverse perinei superficialis muscle and travels medially
- Anastomosis: the transverse perineal branch anastomoses with the inferior rectal arteries, posterior scrotal artery and the contralateral transverse perineal artery 2
-
Supply
- Perineal artery: bulbospongiosus and ischiocavernosus muscles
- Transverse perineal branch: transverse perinei superficialis muscles, perineal body and the posterior bulb of the penis
- Posterior scrotal artery: posterior scrotal skin and dartos muscle
- Posterior labial artery: skin of labia majora and labia minora 2,3
