In both the nervous and the endocrine system signals are passed from one cell to another by chemical communication. In the nervous system, nerve cells send messages electrochemically: this means that chemicals cause an electrical impulse from one cell to another.

What is the main function of nervous system?

The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
