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.
Nervous control of muscular contraction Structure and functions of the nervous system Muscle contraction is initiated by the nervous system which together with the endocrine system controls the human organism. They are responsible for the steadiness of the inner environment and coordination of all the bodily functions. The nerve cell, a neuron, is the basic unit of the nervous system (Fig. 14).
