Nerve Supply of Upper Limb Muscles

This video tutorial covers the muscles of the upper limb and their nerve supply, focusing on the brachial plexus. It details the muscles in the pectoral, scapular, arm, forearm, and hand regions, explaining which nerves supply each muscle group. The video also highlights the exceptions, such as the trapezius muscle, which is supplied by the spinal root of the accessory nerve. The tutorial provides a comprehensive overview of the anatomy and innervation of the upper limb muscles.
