Human Nervous System. The central nervous system (CNS) together with the peripheral nervous system (PNS) together constitute the human neural system. CNS consists of the control and information processing units, the brain and the spinal cord. PNS consists of the nerves that connect peripheral parts to the brain and the spinal cord viz. the CNS.
Central Nervous System. The central nervous system coordinates the functioning of all parts of the human body and is the largest part of the nervous system. It is enveloped by a set of membranes known as meninges that protect the brain and the spinal cord.

Peripheral Nervous System. The peripheral nervous system (PNS) includes all of the parts of the nervous system outside of the brain and spinal cord. These parts include all of the cranial and spinal nerves, ganglia, and sensory receptors.
