Concept explainers
Introduction:
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 that 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. The gustatory or taste cells are nearly banana shaped and possess a tuft of microvilli (apical) referred to as taste hairs, works as receptor surfaces for the
