transversus abdominis muscle, transversalis abdominis muscle
A broad, flat muscle of the abdomen with transverse fibers that is named after the direction of its fibers.

This muscle lies just below the internal oblique, originating from the lumbar fascia, iliac crest, and inguinal ligament.

It spans the area from the pelvis to the abdomen and inserts in the xiphoid cartilage and linea alba.

The transversus abdominis is innervated by the lower thoracic nerves and supplied by the lumbar arteries and this muscle assists in breathing.
