The type II taste bud cells make up about another third of the cells in the taste bud and express G-protein coupled receptors that are associated with chemoreception. They usually express either type 1 or type 2 taste receptors, but one cell might detect different stimuli, such as umami and sweetness. [5]
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.
In a previous video, Ellie tried to pack herself an entire jar of peanut butter and some slices of bread to have a peanut butter sandwich for lunch. The independent 5-year-old also decided to help ...
TrpM5 is a cation channel of the TRP superfamily that is highly expressed in taste buds of the tongue. In vallate and foliate taste buds of transgenic mice expressing TrpM5-GFP (green), two G-protein alpha subunits, G14 (red) and G-gustducin (blue), exist within the population of type II taste cells that express TrpM5.

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]
