The tongue is an important accessory organ in the digestive system. The tongue is used for crushing food against the hard palate, during mastication and manipulation of food for softening prior to swallowing. The epithelium on the tongue's upper, or dorsal surface is keratinised. Consequently, the tongue can grind against the hard palate ...

A first language (L1), native language, native tongue, or mother tongue is the first language a person has been exposed to from birth [1] or within the critical period. In some countries, the term native language or mother tongue refers to the language of one's ethnic group rather than the individual's actual first language.
Lingual papillae, particularly filiform papillae, are thought to increase the surface area of the tongue and to increase the area of contact and friction between the tongue and food. [2] This may increase the tongue's ability to manipulate a bolus of food, and also to position food between the teeth during mastication (chewing) and swallowing.
Definitions of macroglossia have been proposed, including "a tongue that protrudes beyond the teeth during [the] resting posture" and "if there is an impression of a tooth on the lingual border when the patients slightly open their mouths". [5] Others have suggested there is no objective definition of what constitutes macroglossia. [14]
The frenulum (or frenum) of the tongue, tongue web, lingual frenulum, frenulum linguae, or fraenulum [1] is a small fold of mucous membrane extending from the floor of the mouth to the midline of the underside of the human tongue.
Lymphangiomas are far less common in the oral mucosa, usually appearing on the tongue, less commonly the lip at birth or in infancy (1, 2, 4). They are colourless to pale pink and may be nodular projections (1) or resemble 'frog spawn' domes (2). They can cause macroglossia (enlargement of the tongue) (1, 4).
