Lingual papillae (sg.: papilla) are small structures on the upper surface of the tongue that give it its characteristic rough texture. The four types of papillae on the human tongue have different structures and are accordingly classified as circumvallate (or vallate), fungiform, filiform, and foliate.
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 ...
Transient lingual papillitis (TLP) is a medical term for painful, hypertrophic, red, and white lingual papillae on the tongue. [3] TLP is also called lie bumps and fungiform papillary glossitis. This condition has four types: classic form, transient u-shaped lingual papillitis, papulokeratotic variant, and eruptive lingual papillitis. [4]
Embedded in this are numerous papillae, some of which house the taste buds and their taste receptors. [10] The lingual papillae consist of filiform, fungiform, vallate and foliate papillae, [6] and only the filiform papillae are not associated with any taste buds. The tongue can divide itself in dorsal and ventral surface.
There are three types of papillae involved in taste: fungiform papillae, foliate papillae, and circumvallate papillae. (The fourth type - filiform papillae do not contain taste buds). Beyond the papillae, taste receptors are also in the palate and early parts of the digestive system like the larynx and upper esophagus.
Human Von Ebner's gland. Von Ebner's glands, also called Ebner's glands or gustatory glands, are exocrine glands found in the mouth. More specifically, they are serous salivary glands which reside adjacent to the moats surrounding the circumvallate and foliate papillae just anterior to the posterior third of the tongue in its submucosa, anterior to the terminal sulcus.
Median rhomboid glossitis is a condition characterized by an area of redness and loss of lingual papillae on the central dorsum of the tongue, sometimes including lesions of the tongue and palate. It is seen in patients using inhaled steroids and smokers, and is usually a kind of chronic atrophic oral candidiasis , but hematinic deficiency and ...
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.
