The cervical and brachial plexuses both originate from the spinal cord in the neck region. They consist of interconnected spinal nerves. Both plexuses are responsible for innervating specific body regions. The cervical plexus serves the neck and diaphragm, while the brachial plexus serves the shoulder, arm, and hand. They facilitate motor and sensory functions.
