Origin

The deep transverse perineal muscle originates from the internal surface of the ramus of ischium.

Insertion

The fibers of the deep transverse perineal muscle travel medially and insert onto the perineal body.

Key Features & Anatomical Relations

The deep transverse perineal muscle is one of the muscles of the deep perineal space, which itself is found in the urogenital triangle of the perineum. It is a short, thin skeletal muscle. It is located:

- superior to the perineal membrane and the superficial transverse perineal muscle;

- inferior to the levator ani muscle;

- medial to the ischium;

- lateral to the perineal body.

Actions

The deep transverse perineal muscle stabilizes the perineal body and provides structural support to adjacent pelvic and perineal structures (Moore, Dalley and Agur, 2009).

Perineum

ScienceDirect image

The diamond-shaped perineum has the urogenital diaphragm (the triangular layer from the symphysis pubis in the front and then left and right ischial tuberosities, the two bony lumps on which we sit) as its roof and the skin as its floor.
