Deep transverse perineal muscle Muscles of the female perineum. (Transversus perinei visible at center right.) Muscles of male perineum. (Transversus perinei visible at center right.) Latin musculus transversus perinei profundus Gray's subject #120 429 Origin inferior rami of the ischium Insertion its fellow of the opposite side Artery Nerve pudendal nerve Actions Fixation of central tendon of perineum, support of pelvic floor, expulsion of semen in male and last drops of urine in both sexes[1] The Transversus perinei profundus (or deep transverse perineal) arises from the inferior rami of the ischium and runs to the median line, where it interlaces in a tendinous raphé with its fellow of the opposite side.
It lies in the same plane as the Sphincter urethrae membranaceae; formerly the two muscles were described together as the Constrictor urethrae.
