The brachial artery is a major artery located in the upper arm. It is a continuation of the axillary artery and extends down the arm. At approximately the elbow, the brachial artery divides into two terminal branches: the radial artery and the ulnar artery, which supply blood to the forearm, hand, and wrist. The brachial plexus, a network of nerves originating from spinal cord levels C5-T1, also serves the shoulder and upper extremity, providing motor, sensory, and autonomic fibers.123
