Answer 1

Answer:

Spinal nerves branch off from the spinal cord to innervate the rest of the body. These complex networks of nerves enable the brain to receive sensory inputs from the skin and to send motor controls for muscle movements. In the cervical spine, there are eight pairs of spinal nerves labeled C1 to C8, which innervate the neck, shoulder, arm, hand, and more.
