Introduction:
Structures that are specialized for the detection of a stimulus, such as pain and heat, are referred to as a sensory receptor. Such receptors can either be real sense organs or simple nerve endings. Sense organs are involved in the transmission of data (through neurons) to the specific place inside the nervous system. Such sense organs may range from simple microscopic structures, like dendrites, to complex structures, like ear and eye. Receptors can be classified into three categories based on the stimulus origin, modality, and its location in the body. The classification of taste receptors: (i) based on the modality of the stimulus: chemoreceptors; (ii) based on the stimulus origin: exteroceptors; and (iii) based on the location of receptors in the body: specific senses.
