The Roles of the Sensory Neurons, Interneurons, and Motor Neurons

The mammalian nervous system is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system is where signals are generated and received, and the peripheral nervous system provides the avenues for signal dissemination.

Peripheral Nervous System

The main function of the peripheral nervous system is to connect the central nervous system to the limbs and organs. It consists of the nerves and ganglia outside of the brain and spinal cord. The peripheral nervous system is split into a sensory divsion and a motor division.
