Upper limb anatomy in 3D:
shoulder, arm, forearm and hand

The upper limb extends from the shoulder girdle to the fingertips and is adapted for reach and fine manipulation.

Its skeleton comprises the clavicle, scapula, humerus, radius, ulna and the bones of the hand. Muscles are grouped in flexor and extensor compartments. It is supplied by the subclavian artery and its branches and innervated by the brachial plexus (C5–T1).
