The central nervous system (which includes the brain and spinal cord) is encased with bone (the skull and vertebral column) and is bathed with cerebrospinal fluid, which helps to protect and cushion it. The peripheral nervous system, which includes all the other nerves in the body outside of the CNS, is not encased in bone and is not bathed in cerebrospinal fluid.
