In a sensory system, a sensory receptor is a sensory nerve ending that recognizes a stimulus in the internal or external environment of an organism.
Following are the different sensory receptors
Ampullae of Lorenzini respond to electric fields, salinity, and to temperature, but function primarily as electroreceptors
Baroreceptors respond to pressure
Chemoreceptors respond to chemical stimuli
Hydroreceptors respond to changes in humidity
Mechanoreceptors respond to mechanical stress or mechanical strain
Nociceptors respond to damage to body tissues leading to pain perception
Osmoreceptors respond to the osmolarity of fluids (such as in the hypothalamus)
Photoreceptors respond to light
Proprioceptors provide the sense of position
Thermoreceptors respond to temperature, either heat, cold or both
Electromagnetic Receptors's respond to electromagnetic waves
