Document Summary

Netanatomy images: radiographic anatomy>upper limb: 11-16 /cross-sectional anatomy>upper limb: levels 7-8. Oblique head: base of 2nd and 3rd metacarpal. Lateral 2 tendons of flexor digitorum profundus (digits 2 and 3) Medial 2 tendons of flexor digitorum profundus (digits 3 and 4) Flexor mcp and extend ip joints of digits 2-5. Help lumbricals with mcp flexion and ip extension. Muscle facts: none of the hand muscles cross the wrist, opponens m are deep to the abductor and flexor on thenar side // opponnens m is medial to abductor and flexor on hypothenar side. Lumbricals 1-2 are the last motor innervations that median n. does after that it becomes common and proper palmar digital. Palmar fascia thin on the thenar and hypothenar eminences. Palmar aponeurosis lays on top of flexor tendons and superficial palmar arch // what palmaris longus m distally attaches (all considered central compartment of hand)
