As it crosses the Transversus perinæi superficialis 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. [WP,unvetted]. superficial perineal artery NCIT:C52994 artery internal pudendal artery
