Radial Nerve - Branches, Course & Innervation - Human Anatomy | Kenhub

Redial narve recovery time

Where is its course and branches in arm ?
This is only forrarm and in fact I needed info about arm more than this forearm

Radial nerve root value is C5 - C8 ...but extensor carpi radialis brevis innervation is C7 & C8 ..why here C5 & C6 not involved...????

Medial cord not posterior

it is not detailed at all, I'm sorry but you missed 90% of what we need to know about it.
