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 lingual nerve can also be damaged during otologic surgery, causing a feeling of metal taste. Taste loss can vary from true ageusia, a complete loss of taste, to hypogeusia, a partial loss of taste, to dysgeusia, a distortion or alteration of taste. The primary cause of ageusia involves damage to the lingual nerve, which receives the stimuli ...
Less common nerves injuries are on the lingual nerve and mental nerve, which are responsible for tongue and chin sensation respectively. The lingual nerve is affected by the wire placement in the molar region. [51] The mental nerve injury can be caused by the presence of bony spurs. A damage in the nerve may require additional therapy to repair ...

Facebook recently paid 1.4 million Illinois residents $397 in 2022 as part of a class action lawsuit for facial recognition breaches through its “Tag Suggestions” feature, per CNBC.
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).
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 ...
a number of blood vessels and nerves, e.g. the lingual artery and nerve, the hypoglossal nerve and the glossopharyngeal nerve. the sublingual salivary gland. Saliva from the sublingual gland drains through several small excretory ducts in the floor of the mouth. Sometimes a more distinctive duct can be recognized, known as Bartholin's duct.
