**All muscles join via aponeuroses in the '''linea alba''' at midline, which runs from the [[Ribs and Sternum - Anatomy & Physiology#Costae|xiphoid process]] to the [[Pelvis - Anatomy & Physiology#Pelvic Girdle|pelvic symphysis]] via the prepubic tendon, ensheathing the ''rectus abdominus''

**The ''External abdominal oblique'' runs caudoventrally from the lateral surface of the ribs and the lumbar fascia to the linea alba

**The ''External abdominal oblique'' runs caudoventrally from the lateral surface of the ribs and the lumbar fascia to the linea alba. Its caudal border is thickened to form the inguinal ligament and a slit in its aponeurosis forms the superficial inguinal ring.

**The ''Internal abdominal oblique'' runs cranioventrally from the tuber coxae and the thoracolumbar fascia to the linea alba

**The ''Transversus abdominus'' is the deepest muscle of the flank, running dorsoventrally from the inner surface of the last ribs and the transverse processes of the lumbar vertebrae
