Taste bud. The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste (flavor). [1] Taste is the perception stimulated when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue.
The taste buds on the tongue sit on raised protrusions of the tongue surface called papillae. There are four types of lingual papillae; all except one contain taste buds: Fungiform papillae - as the name suggests, these are slightly mushroom-shaped if looked at in longitudinal section. These are present mostly at the dorsal surface of the ...
The misinterpreted diagram that sparked this myth shows human taste buds distributed in a "taste belt" along the inside of the tongue. Prior to this, A. Hoffmann had concluded in 1875 that the dorsal center of the human tongue has practically no fungiform papillae and taste buds, [12] and it was this finding that the diagram describes.
The gustatory cortex is the primary receptive area for taste. The word taste is used in a technical sense to refer specifically to sensations coming from taste buds on the tongue. The five qualities of taste detected by the tongue include sourness, bitterness, sweetness, saltiness, and the protein taste quality, called umami.
The tongue is equipped with many taste buds on its dorsal surface, and each taste bud is equipped with taste receptor cells that can sense particular classes of tastes. Distinct types of taste receptor cells respectively detect substances that are sweet, bitter, salty, sour, spicy, or taste of umami . [ 15 ]

Like the olfactory system, the taste system is defined by its specialized peripheral receptors and central pathways that relay and process taste information.Peripheral taste receptors are found on the upper surface of the tongue, soft palate, pharynx, and the upper part of the esophagus.
Next to the taste receptors in on the tongue, the gut epithelium is also equipped with a subtle chemosensory system that communicates the sensory information to several effector systems involved in the regulation of appetite, immune responses, and gastrointestinal motility. [5]
