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.
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.
The sublingual space is V-shaped, with the apex pointing to the anterior. Its boundaries are: [2] the mucosa of the floor of mouth and the tongue superiorly; the mylohyoid muscle inferiorly; the medial surface of the mandible anterolaterally; the muscles along the base of the tongue (geniohyoid and genioglossus muscles) posteriorly
The lingual nerve supplies general somatic afferent (i.e. general sensory) innervation to the mucous membrane of the anterior two-thirds of the tongue (i.e. body of tongue) (whereas the posterior one-third (i.e. root of tongue) is innervated via the glossopharyngeal nerve (CN IX) [citation needed]), the floor of the oral cavity, and the mandibular/inferior lingual gingiva.
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 ...
Lingual tonsils are located on posterior aspect of tongue which is supplied through: [1] Lingual artery, branch of external carotid artery; Tonsillar artery; Ascending and descending palatine arteries; Ascending pharyngeal branch of external carotid artery
