Answer: The nervous system controls and coordinates all the functions in the body. It carries out its functions in close coordination with the hormonal system. Nerves don’t reach every nook and corner of the body and hence needs assistance from the hormones to control all the parts of the body. Moreover, while the nervous control is somewhat faster, hormonal control is slower. Hormonal control is mainly based on feedback mechanism and tells the body to either pace up or slow down; as per the situation. Nervous control, on the other hand, is more of a direct control. Both of them complement each other. Thus, it can be said that nervous and hormonal systems together perform the function of control and coordination in human beings.
