Themuscular branches of theradial nerve supply thetriceps brachii,anconæus,brachioradialis, andextensor carpi radialis longus, and are grouped as medial, posterior, and lateral.
The medial muscular branches supply the medial head of thetriceps brachii.
That to the medial head is a long, slender filament, which lies close to the ulnar nerve as far as the lower third of the arm, and is therefore frequently spoken of as theulnar collateral nerve.
The posterior muscular branch, of large size, arises from the nerve in the groove between thetriceps brachii and thehumerus.
It divides into filaments, which supply the medial and lateral heads of thetriceps brachii and theanconæus muscles.
The branch for the latter muscle is a long, slender filament, which descends in the substance of the medial head of thetriceps brachii.
The lateral muscular branches supply thebrachioradialis,extensor carpi radialis longus, and the lateral part of thebrachialis.
