Central and peripheral nervous systems are the two components of the nervous system in animals. The central nervous system comprises the brain and spinal cord. The peripheral nervous system comprises the somatic nervous system and the autonomic nervous system. The main difference between central and peripheral nervous system is that the central nervous system receives sensory information and the processed information is sent into effector organs as the response whereas the peripheral nervous system is involved in sending information to the central nervous system and sending responses from the central nervous system into the effector organs.
