The nervous system can be broadly classified into the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS comprises the brain and the spinal cord while all the nerves arising from the CNS make up the PNS. The PNS is further classified into the autonomic nervous system - controls involuntary actions and the somatic nervous system - controls voluntary actions.
