Overview of the cns: anatomy, energy supply. Central nervous system (cns) = brain + spinal cord. Spinal column is bone around spinal cord that protects it. Neurons outside the cns make up the peripheral nervous system. The peripheral nervous system (pns) includes all neurons, and parts of neurons, outside the cns. Pns comprises the somatic nervous system, for control voluntary action via skeletal muscle, and the autonomic nervous system, for visceral functions such as heart rate and breath. Part of the autonomic system is the enteric nervous system, which controls digestion and movements of the gut: gets input from spinal cord, but can also work independently.
