Example: when you step on a nail, your body perceives a stimulus (change in external or internal environment) receptor is the specific thing identifying stimulus, in this case, the skin, then a nervous impulse is generated and is transmitted through a chain of neurons towards central nervous system, sent to the brain where the impulse is interpreted (integration) by the brain, brain will send off new impulse via motor neurons through spinal cord through nerve to muscle to carry out response.
