The radial nerve originates from the posterior cord of the brachial plexus with root values of C5 to C8 and T1. From the brachial plexus, it travels behind the third part of the axillary artery (part of the axillary artery distal to the pectoralis minor).
The Radial Nerve originates from the posterior cord of the brachial plexus and the C5–C8 nerve roots supply it. It provides forearm extension and supination, wrist extension, abduction of the thumb in the plane of the palm, and extension of the digits at their metacarpal–phalangeal joints.
The radial nerve is a mixed nerve that carries both motor and sensory innervation. The motor branches of the radial nerve innervate the long and medial heads of triceps brachii muscle, anconeus muscles, brachialis (lateral half), brachioradialis, and extensor carpi radialis longus muscles.
The Radial Nerve Morphological Data The radial nerve corresponds to the most voluminous termi-nal branch of the brachial plexus. It receives branches from all three of the brachial plexus trunks (Figure R1). Origin The radial nerve constitutes nerve bres coming from the C5, C6, C7, C8 and T1 roots (Figures R and 1 R2). It forms the main ter-
