Definition
Somatic receptors – They include receptors for chemicals, temperature, pain, touch, proprioception and pressure
Visceral receptors – They respond to chemicals, temperature and pressure
Special senses - gustation, olfaction, vision, equilibrium and hearing |

|
Definition
Chemoreceptors – detect specific molecules dissolved in fluid
Thermoreceptors – detect changes in temperature
Photoreceptors – detect changes in light intensity, color and movement of light
Mechanoreceptors – detect physical deformation
Baroreceptors – detect pressure changes within body structures
Nociceptors – detect tissue damage and pain |
