Summary Introduction
Introduction:
The structures that can sense taste stimuli are called as taste buds. The taste buds are very small structures that are present along the region like the edges of the papillae. The taste buds are associated with fungiform, vallate and foliate papillae. The filiform papillae do not have taste buds.
