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.
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 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.
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 ...
In summary, the fibers carried in the ganglion are: Sympathetic fibers from the external carotid plexus, via the facial nerve and its branches. These do not synapse in this ganglion. Preganglionic parasympathetic fibers from the superior salivatory nucleus of the Pons, via the chorda tympani and lingual nerve, which synapse at this ganglion.
The lingual branch of the mandibular division (V3) of the trigeminal nerve supplies non-taste sensation (pressure, heat, texture) to the anterior part of the tongue via general somatic afferent fibers. Nerve fibers for taste are supplied by the chorda tympani branch of the facial nerve via special visceral afferent fibers. [10]
Lingual artery: Nerve: Hypoglossal nerve: Actions: Inferior fibers protrude the tongue, middle fibers depress the tongue, and its superior fibers draw the tip back ...
The superior longitudinal muscle of tongue or superior lingualis is a thin layer of oblique and longitudinal fibers immediately underlying the mucous membrane on the dorsum of the tongue. Structure [ edit ]
