The nervous system of an animal coordinates the activity of the muscles, monitors the organs, constructs and also stops input from the senses, and initiates actions. Prominent participants in a nervous system include neurons and nerves, which play roles in such coordination.
In animals without brains, the nervous system does not generate or conduct thoughts and emotions. Thus it is the system that animates "animals" (sponges are an exception).
