Muscular branches of the radial nerve
|Nerve: Muscular branches of the radial nerve|
|Superficial palmar nerves.|
|Latin||rami musculares nervi radialis|
|Gray's||subject #210 943|
|Innervates||posterior compartment of the arm, mobile wad|
The medial muscular branches supply the medial and long heads of the Triceps 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 the ulnar collateral nerve.
The branch for the latter muscle is a long, slender filament, which descends in the substance of the medial head of the Triceps brachii.
