The anterior oral part is the visible part situated at the front and makes up roughly two-thirds the length of the tongue. The posterior pharyngeal part is the part closest to the throat, roughly one-third of its length. These parts differ in terms of their embryological development and nerve supply. The anterior tongue is, at its apex, thin ...
Anterior lingual glands (also called apical glands) are deeply placed seromucous glands that are located near the tip of the tongue on each side of the frenulum linguae. They are found on the under surface of the apex of the tongue, and are covered by a bundle of muscular fibers derived from the styloglossus and longitudinalis inferior .
Ankyloglossia, also known as tongue-tie, is a congenital anomaly characterised by an abnormally short lingual frenulum; when severe, the tip of the tongue cannot be protruded beyond the lower incisor teeth. [6] There are two generalized classifications of ankyloglossia, anterior and posterior tongue-ties.
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.
In human anatomy, the mouth is the first portion of the alimentary canal that receives food and produces saliva. [2] The oral mucosa is the mucous membrane epithelium lining the inside of the mouth. In addition to its primary role as the beginning of the digestive system, the mouth also plays a significant role in communication.
The mouth is the body orifice through which many animals ingest food and vocalize.The body cavity immediately behind the mouth opening, known as the oral cavity (or cavum oris in Latin), [2] is also the first part of the alimentary canal, which leads to the pharynx and the gullet.
Anatomy of the human mouth, including the frenulum of the tongue. A frenulum / ˈ f r ɛ n j ʊ l əm / or frenum / ˈ f r iː n əm / (pl.: frenula or frena, from the Latin frēnulum, "little bridle", the diminutive of frēnum [1]) is a small fold of tissue that secures the motion of a mobile organ in the body.
Lingual tonsils are covered externally by stratified squamous epithelium (nonkeratinized) that invaginates inward forming tonsillar crypts.Beneath the epithelium is a layer of lymphoid nodules containing lymphocytes.
