Introduction:

The nervous system is categorized into the peripheral nervous system (PNS) and the central nervous system (CNS). CNS comprises the brain and the spinal cord, while PNS is sub-categorized into the Autonomic nervous system (ANS) and somatic nervous system. The innervation of all the tissues other than the skeletal muscles is by way of the ANS. It is also referred to as the vegetative or involuntary nervous system. It is organized into two distinct regions along the CNS, forming the parasympathetic and sympathetic systems.
