ABSTRACT
All of the nervous system that is not brain or spinal cord is referred to as the peripheral nervous system. The somatic nervous system is the part of the peripheral nervous system that mainly serves our skin and skeletal musculature. The somatic nervous system carries information both to the central nervous system, and away from it. In the sensory direction, the somatic nervous system is made up of those sensory nerves that innervate the sense organs in the skin. The somatic nervous system can, itself, be divided into two parts. The spinal nerves enter and leave the central nervous system (CNS) via the spinal cord whereas the cranial nerves enter and leave the CNS via the ventral surface of the brain. These cranial nerves serve the head and the spinal nerves serve the rest of the body. The word nerve here means a bundle of axons that travel together from the central nervous system to another part of the body.
