These are located on top of the taste receptor cells that constitute the taste buds. The taste receptor cells send information detected by clusters of various receptors and ion channels to the gustatory areas of the brain via the seventh, ninth and tenth cranial nerves. On average, the human tongue has 2,000–8,000 taste buds. [2]

The tongue is a muscular organ in the mouth of a typical tetrapod. It manipulates food for chewing and swallowing as part of the digestive process, and is the primary organ of taste. The tongue's upper surface (dorsum) is covered by taste buds housed in numerous lingual papillae.
Circumvallate papilla in vertical section, showing arrangement of the taste-buds and nerves. The circumvallate papillae (or vallate papillae) are dome-shaped structures on the human tongue that vary in number from 8 to 12. They are situated on the surface of the tongue immediately in front of the foramen cecum and sulcus terminalis, forming a ...
"COVID tongue refers to a rare but well-described condition in acute infection where the taste buds are attacked and temporarily damaged by the virus," Dr. Yancey explains. COVID tongue symptoms vary.
Katz calls the process “taste bud rehab,” a term he coined more than a decade ago. “If I asked you to boycott all the desserts in your life, you would probably rebel or fail,” Katz said.
The diagram above depicts the signal transduction pathway of the sweet taste. Object A is a taste bud, object B is one taste cell of the taste bud, and object C is the neuron attached to the taste cell. I. Part I shows the reception of a molecule. 1. Sugar, the first messenger, binds to a protein receptor on the cell membrane. II.
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.
