Wrist and hand: The superficial radial nerve gives rise to branches that spread along the dorsoradial aspect of the wrist and hand and to the thumb and lateral three fingers. The deep branch of radial nerve somewhat terminates into a “psuedoganglion”...
Cubital Fossa/Antebrachium: The radial nerve enters the cubital fossa on the lateral aspect and lies between the brachialis and brachioradialis muscles. It then splits into superficial and deep branches in the forearm. The superficial branch descends across the...
Brachium: After branching from the brachial plexus the radial nerve descends from anterior to the subscapularis, teres major and latissimus dorsi to proceed posteriorly through the triangular space (teres major superiorly, long head of triceps medially and humerus...
Pathway Overview: The radial nerve emerges from nerves C5 through C8 from the brachial plexus. As it emerges from the posterior aspect of the plexus, it is bound with the other terminal branches of the brachial plexus and with the axillary artery by a sheath and is...
Antebrachium: After leaving the cubital tunnel, the ulnar nerve crosses the fibrous tendon band of the flexor carpi ulnaris on its anterior aspect. The ulnar nerve continues distally just deep to the flexor carpi ulnaris muscle until it reaches the wrist. Wrist: The...
