The spinal cord and the brain make up the central nervous system (CNS). Spinal cord nerves carry messages between the brain and the rest of the body.

How does the spinal cord connect to the peripheral nervous system?
The nerve roots then merge into bilaterally symmetrical pairs of spinal nerves. The peripheral nervous system is made up of these spinal roots, nerves, and ganglia. The dorsal roots are afferent fascicles, receiving sensory information from the skin, muscles, and visceral organs to be relayed to the brain.
Where does the spinal cord run through the skull?
The Spinal cord runs through a hollow case from the skull enclosed within the vertebral column. Spinal nerves arise from different regions of the vertebral column and are named accordingly, the regions are – Neck, chest, pelvic and abdominal.
