Transversus Perinei Superficialis

Version 1

Abstract

This muscle is frequently absent or poorly developed. Sometimes it consists of several separate fasciculi, and it may be inserted wholly or in large part into the bulbocavernosus or external anal sphincter. A muscular slip is occasionally found arising from the fascia at the lower border of gluteus maximus or upper fascia lata and inserts under the origin of bulbocavernosus in the albuginea of the bulbous (penile) urethra in males. This variation is not found in females.
