These nerve roots converge to form trunks, which then divide into anterior and posterior divisions, and subsequently recombine to form the three major cords named for their position relative to the axillary artery. The cords then give rise to the terminal branches, including the musculocutaneous, median, ulnar, and radial nerves, which innervate everything from the powerful biceps to the delicate intrinsic muscles of the hand.
Understanding the Brachial Plexus Simple Recovery Timeline
In adults, high-energy trauma can cause avulsion, where the nerve root is torn from the spinal cord, or rupture, where the nerve is severed further away. This intricate network of nerves serves as the primary communication highway between the central nervous system and the entire upper limb.
The goals of rehabilitation are to prevent contractures, maintain joint mobility, and retrain neuromuscular pathways. Anatomy of the Brachial Plexus At its core, the brachial plexus simple anatomy involves the ventral rami of the lower four cervical nerves (C5-C8) and the first thoracic nerve (T1).

This complex braiding of fibers is what allows for the precise and coordinated control of the shoulder, arm, and hand. These tests not only confirm the presence of a lesion but also help to differentiate between a pre-ganglionic injury (near the spine) and a post-ganglionic injury (distal to the nerve root).
