Introduction:

Sensory receptors are either dendrite of a sensory nerve cell or a specialized cell. Every sensory receptor is activated by a particular type of alterations in the environment. The sensory receptors are categorized in different classes on the basis of microscopic structure (free nerve ending or separate cells), type of stimulus detected (mechanoreceptors, nociceptors, chemoreceptors, photoreceptors, or thermoreceptors), as well as origin of stimuli and location of receptors (exteroceptors, proprioceptors, and interoceptors).
