Document Summary

Muscles: psoas major, psoas minor (if present), iliacus, quadratus lumborum distal tendon for iliacus and psoas major together. Iliac crest; iliolumbar ligament (little bit) runs between psis and tp l5. Anterior rami (t12 l4: nerve innervation, action, bilateral, unilateral: Psoas major: proximal attachment, distal attachment, nerve innervation: body and tp t12 l5. Anterior rami l1 l3: lumbar plexus found within psoas major, action: Flex hip; anterior pelvic tilt (by pulling vertebrae forward, increasing lumbar lordosis) Psoas minor: proximal attachment, distal attachment, nerve innervation, action, absent in 40% of people posterior pelvic tilt. Iliacus: proximal attachment, distal attachment, nerve innervation, action: Lesser trochanter of femur (via iliopsoas tendon under inguinal ligament)
