The branches of the lateral cord of the brachial plexus give rise to the lateral pectoral nerve, the musculocutaneous nerve, and the lateral root of the median nerve, providing motor and sensory innervation to the anterior compartment of the arm and forearm. These branches originate from the anterior divisions of C5 and C6 spinal nerves.
