Classification by stimuli detected
- Mechanoreceptors
- found in skin, walls of blood vessels, stomach, bladder, ear
- detect pressure or strecth
- touch, pressure, vibration, hearing, proprioception
(muscle belly), equilibrium & blood pressure
- Pressure is a sustained sensation felt over a larger area than touch
- Result from tactile receptors in deeper tissues & longer
lasting & less variation in intensity than touch sensations
- type II cutaneous mechanoreceptors & lamellated (Pacinian) corpuscles
- Vibration sensations result from rapidly repetitive sensory signals from tactile receptors
- Thermoreceptors
- detect temperature
- Nociceptors
- Detect damage to tissues (pain)
- Photoreceptors
- detect light
- Chemoreceptors
- Detect molecules
- taste, smell & changes in body fluid chemistry
