Muscle Origin Insertion Innervation Action
Iliacus Iliac Fossa Lesser Trochanter Femoral n.
L2 - L3		 Hip: Flexion, ER
L/S (UNIL contraction on fixed femur): I/L spine sidebend
L/S (BIL contraction): Raises trunk from supine position

Origin

Iliac fossa

Insertion

Femur (lesser trochanter)

Innervation

Femoral N. (L2, L3)

Action

  • Hip joint: flexion and external rotation
  • L/S: unilateral contraction (with the femur fixed) flexes the trunk laterally to the same side; bilateral contraction raises the trunk from the supine position

Overview

Stretches
