Quizplus · Accepted Answer

The CNS (central nervous system) is encased with bone (skull and vertebral column) and is bathed with CSF (cerebrospinal fluid), which acts as a cushion and helps to protect the brain and spinal cord. The peripheral nervous system, on the other hand, is not encased with bone but has nerves that connect the CNS to the rest of the body.
