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 hypoglossal nerve, also known as the twelfth cranial nerve, cranial nerve XII, or simply CN XII, is a cranial nerve that innervates all the extrinsic and intrinsic muscles of the tongue except for the palatoglossus, which is innervated by the vagus nerve. [a] CN XII is a nerve with a sole motor function.
Tissue damage to the nerves that support the tongue can cause ageusia, especially damage to the lingual nerve and the glossopharyngeal nerve. The lingual nerve passes taste for the front two-thirds of the tongue and the glossopharyngeal nerve passes taste for the back third of the tongue. The lingual nerve can also be damaged during otologic ...
The lingual vein passes medial to the hyoglossus. The lingual artery passes deep to the hyoglossus. Laterally, in between the hyoglossus muscle and the mylohyoid muscle, lay several important structures (from upper to lower): sublingual gland, submandibular duct, lingual nerve, vena comitans of hypoglossal nerve, and the hypoglossal nerve.
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 ...
The lingual branch of the glossopharyngeal nerve innervates the taste buds of the posterior 1/3 of the tongue and provides general sensation to this same area. The neuron cell bodies whose axons form the nerve, are found in the inferior ganglion of the glossopharyngeal nerve .
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.
