cervical plexus

The cervical plexus is a network of nerves located in the neck that originates from the spinal cord. It supplies sensation and some motor control to parts of the neck, the lower face, and shoulders. These nerves help you feel touch and temperature on your skin, as well as control muscles that move the neck, shoulder, and diaphragm (the muscle important for breathing). The cervical plexus also provides some nerves that help with breathing and supply blood to nearby areas. Overall, it plays a key role in transmitting signals between your brain and neck, face, and shoulder regions.
