The facial nerve connects to taste buds in the anterior third of the tongue. The glossopharyngeal nerve connects to taste buds in the posterior two thirds of the tongue. The vagus nerve connects to taste buds in the extreme posterior of the tongue, verging on the pharynx, which are more sensitive to noxious stimuli such as bitterness. [18]
The bud is formed by at least two main kinds of cells: supporting cells and gustatory cells. The supporting (sustentacular cells) are mostly arranged like the staves of a cask, and form an outer envelope for the bud. Some, however, are found in the interior of the bud between the gustatory cells.
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 .
Taste bud. The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste. [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.
Taste cells synapse with primary sensory axons that run in the chorda tympani and greater superficial petrosal branches of the facial nerve (cranial nerve VII), the lingual branch of the glossopharyngeal nerve (cranial nerve IX), and the superior laryngeal branch of the vagus nerve (Cranial nerve X) to innervate the taste buds in the tongue ...

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.
