Illustration of a taste bud. A taste bud is composed of taste receptor cells, embedded into the lingual epithelia. Gustatory transduction takes place in taste receptor cells that lie in taste buds, which are located predominantly on the tongue and soft palate. Taste receptor cells are small bipolar cells with no axon. The taste receptors are located on microvilli at the apical surface of taste receptor cells. These microvilli gain access to the oral cavity through a taste pore.
