GENERAL HISTOLOGY

Detailed explanation-1: -INTRODUCTION. The chemoreceptors of taste and smell are closely related; in fact one receptor type, the Lewis acid receptor is common to both the taste (gustatory) and smell (olfactory) modalities.

Detailed explanation-2: -Every food or drink that you put in your mouth has particular chemical components, and these chemicals are detected by special receptors called chemoreceptors. These chemoreceptors are contained within taste buds on the surface of the tongue.

Detailed explanation-3: -Both odors and tastes involve molecules that stimulate specific chemoreceptors. Although humans commonly distinguish taste as one sense and smell as another, they work together to create the perception of flavor. A person’s perception of flavor is reduced if he or she has congested nasal passages.

Detailed explanation-4: -Most chemoreceptors expressed in olfactory organs are G-protein coupled receptors (GPCRs) and can be classified into two major categories: odorant receptors (ORs) and pheromone receptors, which principally detect general odors and pheromones, respectively.
