Nervous System

                                         Nervous system 

The nervous system is a very complex system that registers events in the environment and in the organism. The whole system is composed of the cerebrum, cerebellum, extension cord and nerves.

Part of the nervous system that receives events from the environment, respond to them and then sends impulses call cerebrospin nervous system. It is divided into the central nervous system (large and small brain, extended and spinal cord) and peripheral nervous system (vertebrate nerve or nerves). There are two types of nerves and sensitive that bring sensations to the brain and spinal cord and motor performing a reverse function, ie implement stimulus from the brain to the peripheral parts of the body.Part of the nervous system that regulates events in the organism, and without the influence of the will we call autonomous or vegetative nervous system.This system regulates the activities of the internal organs (heart, lungs, kidneys and other.)
