• Nature of stimulus
• Mechanoreceptor – distortion of the surrounding tissues
• Chemoreceptor – chemical substances in interstitial fluids entero receptor--- your stomach telling you you are not hungry anymore • Photoreceptor - light
• Thermoreceptor - temperature • Origin of stimulus proprio receptors--- joints and shit. • Exteroreceptors – from outside of the body
