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.
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] Sharp lateral movement of the head triggers the pain, usually lasting from a few seconds to a few minutes. Headaches may occur with the onset ...
Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.

Some causes of a burning mouth sensation may be accompanied by clinical signs in the mouth or elsewhere on the body. For example, burning mouth pain may be a symptom of allergic contact stomatitis . This is a contact sensitivity ( type IV hypersensitivity reaction) in the oral tissues to common substances such as sodium lauryl sulfate ...
The effect it has on taste buds can impact how you enjoy food for a bit. "COVID tongue may represent loss of taste buds or papillae on the lining of the tongue," Dr. Mehdizadeh says.
The tongue may traumatized by mechanical, thermal, electrical or chemical means. A common scenario is where the tongue is bitten accidentally whilst a local anesthetic inferior alveolar nerve block is wearing off. The tongue may develop scalloping on the lateral margins, sometimes termed crenated tongue.
The nerve arises from the hypoglossal nucleus in the medulla [1] [2] as a number of small rootlets, pass through the hypoglossal canal and down through the neck, and eventually passes up again over the tongue muscles it supplies into the tongue. The nerve is involved in controlling tongue movements required for speech and swallowing, including ...
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 ...
