•In a very general sense, the NS can be thought of as having 3 essential roles: • The components of the NS responsible for carrying out those roles are: sensing, integrating, and responding. The sensory component The integrative component The motor component detects changes that occur both outside and inside the body. interprets and processes the information that arrives from the sensory component carries out changes based on the interpretation by the integrative component of the nervous system
