The transversus abdominis is the most internal of the lateral abdominal wall muscles. The fascicles generally are transversely oriented. The transversus abdominis arises from the lateral iliopubic tract, the iliac crest, the lumbodorsal fascia, and the caudad six ribs. It inserts principally into its aponeurosis and fuses with the internal oblique aponeurosis to become the posterior rectus sheath.
