Filiform papilla, magnified. Filiform papillae are the most numerous of the lingual papillae. [1] They are fine, small, cone-shaped papillae found on the anterior surface of the tongue. [3] They are responsible for giving the tongue its texture and are responsible for the sensation of touch. Unlike the other kinds of papillae, filiform papillae ...
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 ...
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.
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.
The chorda tympani innervates the fungiform papillae on the tongue. [11] According to a study done by Sollars et al. in 2002, when the chorda tympani has been transected early in postnatal development some of the fungiform papillae undergo a structural change to become more “filiform-like”. [ 12 ]
The sublingual papilla or sublingual fold is a small fold of soft tissue located on each side of the lingual frenulum. [1] The sublingual papilla marks the site of the sublingual gland [ 2 ] with its major sublingual duct [ 3 ] and its minor sublingual ducts [ 4 ] opening upon the papilla.
