The perineal artery (superficial perineal artery) arises from the internal pudendal artery, and turns upward, crossing either over or under the superficial transverse perineal muscle, and runs forward, parallel to the pubic arch, in the interspace between the bulbocavernosus 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 Transversus perinæi superficialis and the structures between the anus and the urethral bulb.

The blood vessels of the anal sac in the domestic cat--A. rectalis caudalis and A. perinealis ventralis, from which the former arises--are visceral blood vessels. A rectalis caudalis, being the origin of anal sac arteries, facilitates the blood supply of the anal sac, while the duct of the anal sac
