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 wide variety of other causes can lead to damage of the nerve. These include surgical damage, medullary stroke, multiple sclerosis, Guillain-Barre syndrome, infection, sarcoidosis, and presence of an ectatic vessel in the hypoglossal canal. [15] [16] Damage can be on one or both sides, which will affect symptoms that the damage causes. [2]
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 ...
Injury to the chorda tympani nerve leads to loss or distortion of taste from anterior 2/3 of tongue. [13] However, taste from the posterior 1/3 of tongue (supplied by the glossopharyngeal nerve) remains intact. The chorda tympani appears to exert a particularly strong inhibitory influence on other taste nerves, as well as on pain fibers in the ...
She experienced partial relief of symptoms after recovery. Examination of the resected nerve fibers showed loss of both myelinated and unmyelinated nerve fibers, this is a possible explanation for the symptoms associated with NTS, however, further study is needed for a definitive answer. [14]
These lesions typically damage the cranial nerves leading to both motor and sensory deficits. The cranial nerves that are impaired include the following; Cranial Nerve (CN) V (the trigeminal nerve ), CN VII (the facial nerve ), CN IX (the glossopharyngeal nerve ), CN X (the vagus nerve ), and CN XII (the hypoglossal nerve ).
Nerve growth factor (NGF) typically has a low level of expression in nerves that are healthy and not growing or developing, but in response to nerve injury NGF expression increases in Schwann cells. This is a mechanism to increase growth and proliferation of Schwann cells at the distal stump in order to prepare for reception of the regenerating ...
The lingual nerve which anaesthetising stops sensation to the lingual aspect of the gingiva, floor of the mouth and the tongue to the midline on that particular side Local anaesthetic is used routinely for dental procedures in oral surgery, restorative, periodontal, and prosthetic dentistry.
