Explanation:
The nervous system is divided into the central nervous system (CNS) & peripheral nervous system (PNS). The brain and the spinal cord comprise the central nervous system. The peripheral nervous system serves the rest of the body and they branch from the spinal cord. Ii is in the peripheral nervous system that you'll find motor and sensory neurons. The sensory neurons take information to the CNS to be processed. After processing information, the CNS sends back information through the motor neuron of the PNS indicating which action to be taken based on the ‘input’ information.
