The central nervous system communicates with the body by means of nerves that exit the CNS from the brain (cranial nerves) and spinal cord (spinal nerves). These nerves, together with aggregations of cell bodies located outside the CNS, constitute the peripheral nervous system.
As mentioned in chapter 7, the peripheral nervous system (PNS) consists of nerves (collections of axons) and their associated ganglia (collections of cell bodies). Although this chapter is devoted to the CNS, the CNS cannot function without the PNS. This section thus serves to complete our discussion of the CNS and introduces concepts pertaining to the PNS that will be explored more thoroughly in later chapters (particularly chapters 9, 10, and 12).
