Nerves of the Upper Limb

Overview

The nerve supply of the upper limb underpins all sensory and motor function. This section explains the formation and branching of the brachial plexus and the pathways of its major terminal nerves.

Key Structures

Articles cover the brachial plexus, its roots, trunks, divisions and cords, followed by detailed pages on the axillary, musculocutaneous, median, radial and ulnar nerves. The cutaneous distribution and functional testing of each nerve are described alongside relevant clinical signs.

Clinical Relevance and Learning Focus

Understanding peripheral nerve anatomy is fundamental for localising lesions and assessing neurological injury. The section connects structural pathways to common clinical presentations such as carpal tunnel syndrome and radial nerve palsy.
