Concept explainers
Introduction:
Structures that are specialized for the detection of a stimulus, such as pain and heat, are referred to as a sensory receptor. 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. The taste sense is also referred to as gustation, which begins with the taste buds (about 4000). The taste buds are composed of sensory cells, which are involved in chemical stimulation. These taste buds are lemon shaped, group of cells (50 to 150), and include supporting cells, taste cells, and basal cells.
