Brachial Plexus

What is the brachial plexus? The brachial plexus provides somatic motor and sensory innervation to the upper extremity, including the scapular region. As the brachial plexus travels through the posterior triangle of the neck into the axilla, arm, forearm, and hand, it contains various named regions based on how the plexus is formed.
