Nervous system

To provide the correct response to a stimulus, it is necessary that all the organs work together in a proper coordinated manner. This working together of various organs in a systematic, controlled and efficient way to produce proper response to various stimuli is called coordination. In animals including human the coordination between the various cells and organs is essential for their diverse activities to maintain physiological balance called homeostasis. In this unit we shall learn about one of the major regulatory systems the nervous system and its control over the body activities.
