The perineal artery (superficial perineal artery) arises from the
superficial transverse perineal muscle, and runs forward, parallel to the pubic arch, in the interspace between the bulbospongiosus and ischiocavernosus muscles, both of which it supplies, and finally divides into several posterior scrotal branches which are distributed to the skin and dartos tunic of the scrotum
.
As it crosses the superficial transverse perineal muscle it gives off the transverse perineal artery which runs transversely on the cutaneous surface of the muscle, and anastomoses with the corresponding vessel of the opposite side and with the perineal and
inferior hemorrhoidal arteries
.
It supplies the
urethral bulb
