Brachial Plexus
The brachial plexus is a complex network of nerves that originates from the spinal cord in the neck, specifically the cervical and thoracic regions (C5 to T1). It extends through the neck, into the axilla (armpit), and down the arm. The primary function of the brachial plexus is to control the muscles and transmit sensory signals (feeling) to the shoulder, arm, and hand.
