What are sensory receptors?

Sensory receptors are structures specialized in the acquiring of information, such as temperature, mechanical pressure, pH, chemical environment and luminosity, transferring them to the central nervous system. Sensory receptors might be specialized cells, e.g., the photoreceptors of the retina, or specialized interstitial structures, for instance the vibration receptors of the skin. In this last case they transmit information to dendrites of sensory neurons linked to them. There are also sensory receptors that are specialized terminations of neuronal dendrites (e.g., the olfactory receptors).
