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 ...

A single taste bud is innervated by several afferent nerves, while a single efferent fiber innervates several taste buds. [24] Fungiform papillae are present on the anterior portion of the tongue while circumvallate papillae and foliate papillae are found on the posterior portion of the tongue. The salivary glands are responsible for keeping ...
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.
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.
