ORGANIZE! Posterior Forearm Muscle Innervation

The video tutorial explains the innervation of the extensor muscles in the posterior compartment of the forearm, focusing on the radial nerve and its branches. It introduces the rule of 222, which helps in understanding the innervation pattern of muscles before and after the elbow joint. The radial nerve bifurcates into a superficial sensory branch and a deep motor branch, which further becomes the posterior interosseous nerve. The tutorial details the muscles innervated by each branch, emphasizing the importance of understanding the radial nerve's pathway.
