Detailed explanation-1: -Your central nervous system includes two organs, your brain and spinal cord. Your peripheral nervous system is everything else and includes nerves that travel from your spinal cord and brain to supply your face and the rest of your body.
Detailed explanation-2: -Peripheral nerves reside outside your brain and spinal cord. They relay information between your brain and the rest of your body.
Detailed explanation-3: -There are 31 pairs of spinal nerves and roots. Eight pairs of cervical nerves exit the cervical cord at each vertebral level. One member of the pair exits on the right side and the other exits on the left.

Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.
