Document Summary

Mid-layer: composed of extensor carpi radialis longus / flexor digitorum. Lateral / distal humerus second metacarpal. Medial epicondyle middle phalange of each finger. Deep layer: composed of supinator, flexor policis longus, pronator. Proximal radius distal phalynx of the thumb. Distal shaft of ulna distal shaft of radius. Proximal ulna distal phalynx of each finger. Lateral epicondyle distal / middle phalanges of each finger. Lateral epicondyle tendon of the fifth phalange. A pocket that is created when contracting the deep posterior forearm. Composed on the extensor pollicis longus, abductor pollicis longus, and extensor pollicis brevis. Also allow you to touch thumb to baby finger. Adduct the fingers toward the middle finger. Abduct the fingers away from the middle finger. Nerves of the leg: each nerve innervates a different region. Femoral, obturator, gluteal, sciatic, tibial, fibular, plantar. Psoas: transverse processes of lumbar vertebrae less trochanter. Iliacus: iliac fossa / sacrum lesser trochantor. Iliopsoas: consists of the psoas and iliacus.
