pathway

stimulus = external or internal change

sensory receptors = convert stimuli into electrical signals

neurons = bring these signals to your brain (impulses)

effectors = are told how to react by your brain (via impulses through neurons)  that's your response

responses

voluntary => you decide to react (skeletal muscle)

involuntary => you have no control over your reaction (smooth muscle that contracts, e.g. when you'r stomach starts to growl)
