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 moves forward lateral to the hyoglossus and medial to the stylohyoid muscles and lingual nerve. [5] It continues deep to the genioglossus muscle and continues forward to the tip of the tongue. It distributes branches to the intrinsic and extrinsic muscle of the tongue innervates as it passes in this direction, and supplies ...
There is an interval between superior pharyngeal constrictor and middle pharyngeal constrictor, this space contains glossopharyngeal nerve, lingual nerve and the stylopharyngeus muscle. [2] The superior fibers arch beneath the levator veli palatini muscle and the Eustachian tube. [citation needed]
If cranial nerve 10 is injured, the soft palate does not rise when the mouth is opened. Tongue. All sides of the tongue are assessed. To inspect the dorsal side (top ...
Traveling with the lingual nerve, the fibers of chorda tympani enter the sublingual space to reach the anterior 2/3 of the tongue and submandibular ganglion. [ 4 ] The special sensory fibers originate from the taste buds in the anterior 2/3 of the tongue and carry taste information to the nucleus of solitary tract of the brainstem , where taste ...
The genioglossus is one of the paired extrinsic muscles of the tongue.It is a fan-shaped muscle that comprises the bulk of the body of the tongue. It arises from the mental spine of the mandible; it inserts onto the hyoid bone, and the bottom of the tongue.

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 ...
