  1. Iliopsoas
    • Origin:
      • Psoas Major
        • Transverse processes of T12-L5 & the lateral aspects of the intervertebral discs
      • Psoas Minor
        • Side of T12+L1 & IV intervertebral disc between
      • Iliacus
        • Iliac fossa, base of sacrum
    • Insertion:
      • Psoas Major
        • Lesser trochanter of the femur
      • Psoas Minor
        • Pectineal line & iliopectineal eminence (lesser trochanter of the femur)
      • Iliacus
        • Lesser trochanter of the femur (lowermost surface)



    • Major Arteries:
      • Psoas Major
        • Lumbar branch of iliolumbar artery
      • Psoas Minor

      • Iliacus
        • Medial femoral circumflex artery
        • Iliac branch of iliolumbar artery


    • Neural Innervation:
      • Psoas Major
        • Lumbar plexus via anterior branches of L1-L3 nerves
      • Psoas Minor
        • Lumbar plexus
      • Iliacus
        • Femoral nerve (L2-L3)
        • Concentric Functions:
          • Hip flexion & external rotation

        • Eccentric Functions:
          • Decelerates hip extension
          • Decelerates femoral internal rotation at heel strike

        • Isometric Function:
          • Assists in stabilizing the lumbar spine during functional movements
