Supporting cells |
The supporting cells form the capsules surrounding the taste receipt cells. These cells support and protect the receptor cells. |
|
|
Taste Receptor Cells |
There are approximately 50 receptor cells in each taste bud. A receptor cell has microvilli, called "taste hair", protruding through a pore on the apical surface of the taste bud. These hairs are the receptor surface for taste stimuli. |
|
|
Basal Cell |
These cells are found peripherally on the base of the taste bud. They develop into supporting cells and then into receptor cells which live about 10 days. |
|
|
Filiform Papillae |
These are small, spike-like projections found all over the tongue. They are the most abundant papillae, but lack taste buds. They roughen the tongue and aid in food manipulation. |
|
|
Foliate Papillae |
These papillae form parallel bands on the sides of the posterior two-thirds of the tongue. They have few taste buds. |
|
|
Fungiform Papillae |
These papillae, as the name implies, are mushroom-shaped projections found all over the tongue, although they tend to be concentrated on the tip and sides. Each papillae has about five taste buds. |
|
|
Vallate Papillae |
These are large circular papillae with a depression in the middle. There are about 12 of them arranged in a V-shaped row on the back of the tongue. They contain from 100 to 300 taste buds. |
