Upper limb anatomy in 3D:
nerves

The nerves of the upper limb arising from the brachial plexus: musculocutaneous, median, ulnar, radial and axillary nerves.

The brachial plexus is organised into roots, trunks, divisions, cords and terminal branches. The musculocutaneous nerve supplies the anterior arm, the median and ulnar nerves the anterior forearm and hand, the radial nerve the posterior arm and forearm, and the axillary nerve the deltoid and teres minor.
