For example, a vallate papilla may contain 250 taste buds, while the number of taste buds may reach 1600 in the fungiform papilla. Taste buds contain the taste receptor cells, which are also known as gustatory cells. The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, the cheek and epiglottis.
