No, the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves outside the central nervous system) work together to coordinate communication throughout the body. The central nervous system processes information and sends commands to the peripheral nervous system to carry out responses.
A simple division into central and peripheral nerves is the kind of nervous system that a grasshopper has. The central nervous system relies upon a central nerve cord whose chain of neurons, known as ganglia, are segment-specific in control. The peripheral nervous system requires coordination of a motor system to tell muscles how to act and of a sensory system to tell the grasshopper of in- and out-of-body events.
