Anatomy
| Exteroreceptors | (location) respond to stimuli originating in external environment(skin) |
| Interoreceptors | (location) respond to changes in body's internal environment |
| Thermoreceptors | (modality) sense changes in temp |
| Chemoreceptors | (modality) sense changes in chemicals |
| Mechanorecpetors | (modality) mechanical stress; pressure, gravity |
| Noicereceptos | (modality) sense tissue damage (pain) |
| Photoreceptors | (modality) Photoreceptors (eyes) |
| Free Nerve Endings | Psuedo-Unipolar neuron w/ dendrites as sensory receptors |
| Encapsulated Nerve Endings | Unipolar neuron w/ encapsulated dendrites |
| Seperate Sensory Cell | synapsing directly onto a neuron |
| Neuron w/ Peripheral Processes | the dendrites are located at the peripheral end |
| (Cutaneous) Free Nerve Endings | skin; pain, temp, touch; slow; |
| (Cutaneous) Merkel Cells | fingertips/lips; light touch; slow; |
| (Cutaneous) Meissners Corpuscles | fingertips/lips; light touch, vibration; Rapid |
| (Cutaneous) Ruffini Corpuscles | deep in dermis; skin stretch; slow |
| (Cutaneous) Krauses Corpsucles | small oval shaped; dermis; cold temps; Rapid |
| (Cutaneous) Pacinian Corpuscles | deep dermis; vibration, deep pressure; rapid |
