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.
A burning sensation in the mouth may be primary (i.e. burning mouth syndrome) or secondary to systemic or local factors. [1] Other sources refer to a "secondary BMS" with a similar definition, i.e. a burning sensation which is caused by local or systemic factors, [16] or "where oral burning is explained by a clinical abnormality". [17]
Neck-tongue syndrome (NTS), which was first recorded in 1980, [1] is a rare disorder characterized by neck pain with or without tingling and numbness of the tongue on the same side as the neck pain. [2]
Lingual thyroid; Cleft tongue (bifid tongue) - completely cleft tongue is a rare condition caused by a failure of the lateral lingual swellings to merge. [4] More common is an incompletely cleft tongue, appearing as midline fissure. This is normally classed as fissured tongue.
The pharyngeal part is supplied by the glossopharyngeal nerve and the oral part is supplied by the lingual nerve (a branch of the mandibular branch (V3) of the trigeminal nerve) for somatosensory perception and by the chorda tympani (a branch of the facial nerve) for taste perception. Both parts of the tongue develop from different pharyngeal ...
Smooth, shiny appearance of the tongue, caused by loss of lingual papillae. Tongue color changes, usually to a darker red color than the normal white-pink color of a healthy tongue. Tongue swelling. Difficulty with chewing, swallowing, or speaking (either because of tongue soreness or tongue swelling). Burning sensation. [2]
Geographic tongue, also known by several other terms, [note 1] is a condition of the mucous membrane of the tongue, usually on the dorsal surface. It is a common condition, affecting approximately 2–3% of the general population.
Anaesthetic injected near the mandibular foramen to block the inferior alveolar nerve and the nearby lingual nerve (supplying the tongue). This causes loss of sensation on the same side as the block to: the teeth (inferior alveolar nerve block) the lower lip and chin (mental nerve block) front two-thirds of the tongue (lingual nerve block).
