In linguistics, specifically articulatory phonetics, tongue shape describes the shape that the tongue assumes when it makes a sound. Because the sibilant sounds have such a high perceptual prominence, tongue shape is particularly important; small changes in tongue shape are easily audible and can be used to produce different speech sounds, even within a given language.
The fimbriated fold of tongue, also plica fimbriata, is a slight fold of the mucous membrane on the underside of the tongue which runs laterally on either side of the frenulum. The free edge of the fimbriated fold occasionally exhibits a series of fringe-like processes. (Fimbria is Latin for fringe).
Foliate papillae are short vertical folds and are present on each side of the tongue. [2] They are located on the sides at the back of the tongue, just in front of the palatoglossal arch of the fauces, [4] [2] There are four or five vertical folds, [2] and their size and shape is variable. [4]
The lesions usually change in shape and size, and migrate to other areas, sometimes within hours. [10] The condition may affect only part of the tongue, with a predilection for the tip and the sides of the tongue, [4] or the entire dorsal surface at any one time. The condition goes through periods of remission and relapse.
The tongue is one of the primary articulators in the production of speech, and this is facilitated by both the extrinsic muscles that move the tongue and the intrinsic muscles that change its shape. Specifically, different vowels are articulated by changing the tongue's height and retraction to alter the resonant properties of the vocal tract .
The tongue's intrinsic muscles allow some people to form their tongues into specific shapes. Rolling the tongue into a tube shape is often described as a dominant trait with simple Mendelian inheritance , and it is commonly referenced in introductory and genetic biology courses, although there is some disagreement.
