At a more integrative level, the primary function of the nervous system is to control the body. It does this by extracting information from the environment using sensory receptors, sending signals that encode this information into the central nervous system, processing the information to determine an appropriate response, and sending output signals to muscles or glands to activate the response.
The autonomic nervous system is often considered to be in control of the unconscious functions of the body. Regulation of heart rate, blood pressure, muscle tone and the gastrointestinal tract are among the key roles of this system. Within the autonomic nervous system, there is a classic separation into the sympathetic and parasympathetic divisions.
