Key facts about the radial nerve
Origin
----------
Posterior cord of the brachial plexus (from the ventral rami of C5-T1)
Muscular innervation
---------------------------------
Arm muscles: triceps, anconeus, brachioradialis,
Forearm muscles: extensor carpi radialis longus, extensor carpi radialis brevis, supinator, extensor digitorum, extensor digiti minimi, extensor carpi ulnaris, abductor pollicis longus, extensor pollicis brevis, extensor pollicis longus, extensor indicis
Mnemonic
-----------------
'Radial nerve innervates the BEST muscles' (Brachioradialis, Extensors, Supinator, Triceps)
Sensory innervation
--------------------------------
Inferior lateral cutaneous nerve of arm: lower outer aspect of the arm
Posterior cutaneous nerve of the arm: posterior surface of the arm
Posterior cutaneous nerve of the forearm: central, posterior aspect of the forearm
Superficial branch of the radial nerve: thenar eminence and dorsal aspect of the radial 3 and half digits of the hand
