Most taste buds on the tongue and other regions of the mouth can detect umami taste, irrespective of their location. (The tongue map in which different tastes are distributed in different regions of the tongue is a common misconception.)
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 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.

Its taste, though difficult to pinpoint, can be described as “a combination of bitter, salty, and a little sour,” says University of Southern California neuroscientist Emily Liman, whose team ...
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]
The same paper included a taste bud distribution diagram that showed a "taste belt". [9] In 1974, Virginia Collings investigated the topic again, and confirmed that all the tastes exist on all parts of the tongue. [10] Into the late 1990s tongue map experiments were a teaching tool in high school biology classes.
