Document Summary

Psoas major originates from t12-l5 of the transverse process and vertebral bodies. It inserts onto the lesser trochanter of femur. Illiacus originates from the iliac fossa and inserts onto the lesser trochanter of the femur. Quadratus lumborum - originates from the iliac crest and inserts onto 12th rib and l1-4 transverse process. External run diagonally down towards midline (pants pockets). Originate from ribs 5-12 and inserts onto pubic tubercle, linea alba and iliac crest. Internal runs diagonally towards the side (laterally). originates from thoracolumbar fascia, iliac crest and spine. Rectus abdominis fibres run directly down the abdomen. Origin from pubic crest and insert onto costal cartilages of ribs 5-7 and xiphoid process. Rectus sheath this is a aponeurotic sheet formed by oblique insertions. Artery superior epigastric artery: this is a continuation from the internal thoracic artery. Inferior epigastric artery: arises from the external iliac artery. Nerve intercostal nerve (7-11), subcostal nerve, iliohypogastric and ilioinguinal.
