types of taste receptors
The gustatory system consists of taste receptor cells in taste buds. Taste buds, in turn, are contained in structures called papillae. There are three types of papillae involved in taste: fungiform papillae, foliate papillae, and circumvallate papillae.(The fourth type-filiform papillae do not contain taste buds).ombinations of these receptors in dimers or other complexes contributes to different perceptions of taste. Visual, olfactive, âsapictiveâ (the perception of tastes), trigeminal (hot, cool), mechanical, all contribute to the perception of taste.
