Detailed explanation-1: -To carry out its normal role, the nervous system has three overlapping functions. Monitoring changes. Much like a sentry, it uses its millions of sensory receptors to monitor changes occurring both inside and outside the body; these changes are called stimuli, and the gathered information is called sensory input.
Detailed explanation-2: -Millions of sensory receptors detect changes, called stimuli, which occur inside and outside the body. They monitor such things as temperature, light, and sound from the external environment.
