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.
Smooth muscle, such as in the digestive system, is also controlled by the autonomic nervous system. Like heart muscle, it is not under our conscious control. The SNS is responsible for controlling voluntary body movements, such as movement of the arms and legs. It is also responsible for receiving sensory information such as touch, hearing, and sight. The SNS contains neurons that connected with the skeletal muscles, skin, and sense organs. Neurons that control skeletal muscle and organs are called motor neurons.
