Concept:The central nervous system (CNS) is the main control center of the body.Explanation:The nervous system is divided into two parts based on location: the central nervous system (CNS) and the peripheral nervous system (PNS).The CNS processes all sensory information and sends motor commands.It is made up of two main parts: the brain and the spinal cord.The PNS connects the CNS to the rest of the body.Therefore, the CNS consists of both the brain and the spinal cord.
