Parts of nervous system (central and peripheral: somatic, autonomic) (picture)

The nervous system is divided into the central nervous system (CNS) — the brain and spinal cord and into peripheral nervous system (diagram 142). The peripheral nervous system is a part of the nervous system that is placed outside of the brain and spinal cord. The central nervous system via the peripheral one performs regulation of functions of different systems, organs and tissues. Craniocerebral (12 pairs), spinal nerves (31 pairs) and peripheral nerve plexus belong to the peripheral nervous system.

The peripheral nervous system is functionally divided into somatic and autonomic. The somatic nervous system — is a part of the nervous system that allows connection of the central nervous system with the skin, muscles, tendons and ligaments, with the environment due to skin and muscle sensitivity, and manages voluntary contractions of skeletal muscles. The vegetative (autonomic) nervous system directs the work of the internal organs. Taken from http://worldofschool.org
