Brachial plexus
The brachial plexus is the network of nerves that supplies the upper limb. It is formed by the anterior rami of spinal nerves C5 to T1, which merge and split through trunks, divisions, and cords before giving rise to the nerves of the shoulder, arm, forearm, and hand.
The brachial plexus nerves in the AnatoMemory reference are listed below: the five terminal branches first, followed by key proximal branches. Each card covers the roots, course, motor and sensory territory, and the injury pattern each nerve is known for.
