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 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 .
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 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 ...
The ganglion 'hangs' by two nerve filaments from the lower border of the lingual nerve (itself a branch of the mandibular nerve, CN V 3). It is suspended from the lingual nerve by two filaments, one anterior and one posterior. Through the posterior of these it receives a branch from the chorda tympani nerve which runs in the sheath of the ...
The risk associated with wisdom tooth surgery is commonly accepted to be 2% temporary and 0.2% permanent. However, this risk assessment is not concrete as the same source [citation needed] is cited for lingual nerve paresthesia. It is well documented that inferior alveolar nerve injury is more common than lingual nerve injury.
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.
The transverse muscle of tongue (transversus linguae) is an intrinsic muscle of the tongue. [1] It consists of fibers which arise from the median fibrous septum.It passes laterally to insert into the submucous fibrous tissue at the sides of the tongue.
