What Is the Lingual Nerve?

One of the branches of the mandibular nerve. The lingual nerve belongs to the sensory nerve, in front of the inferior alveolar nerve, and arches downward along the outside of the hyoid hyoid muscle to the tip of the tongue. The mucous membrane distributed in the front of the tongue 2/3 receives the general sensation of the mucous membrane; the taste fibers from the tympanic cord also pass through this nerve to the fungal nipples and receive the taste in the front of the tongue 2/3.

Local anatomy of the lingual nerve

Mandibular nerve

One of the three branches of the trigeminal nerve. It is a mixed nerve that exits the cranial cavity through a ruptured hole (horse, pig) or oval hole (bovine, carnivorous beast). , Buccal nerve, ear-temporal nerve, lingual nerve, and mandibular alveolar nerve. The first five branches are motor nerves, which are distributed in the masticatory muscles (wing muscle, masseter muscle, temporal muscle, mandibular hyoid muscle, and digastric muscle); the last four branches are sensory nerves, which are distributed in the buccal skin, mucosa and glands. Lips and palate, mandibular teeth, gums and alveolar, tongue and tongue mucosa. Mandibular dental surgery can anesthetize the alveolar nerve at the mandibular foramen on the inside of the mandible.

It is a mixed nerve that penetrates from the oval hole and has two large and small roots. The larger one is the sensory root, starting from the lower corner of the half moon. The smaller one is the motor root, and the oval hole appears below the menstrual period, and merges with the sensory root. After the two are combined, the spinal foramen nerve and the inner pterygoid nerve are issued. The spinal nerve penetrates the spinal foramen and is distributed in the dura mater, and the inner pterygoid muscle is distributed to the inner pterygoid. Then divided into two shares before and after.

(1) Anterior thigh: small, mainly motor nerves, walking on the deep side of the external pterygoid muscle, divided into the masticatory nerve, deep temporal nerve, external pterygoid nerve and buccal nerve. The masticator nerve passes through the upper edge of the external pterygoid muscle, passes through the mandibular notch between the temporal muscle and the mandibular joint, and is distributed in the masticator and mandibular joint. The deep temporal nerve passes through the upper edge of the extrapterygoid muscle and enters the deep side of the temporal muscle to the muscle. External pterygoid nerve originates from the anterior femoral or buccal nerve and is distributed on the deep side of the external pterygoid muscle. The buccal nerve, or long buccal nerve, is a sensory nerve that passes between the two heads of the external pterygoid muscles, goes down the anterior edge of the mandibular branch on the inside of the coracoid process, and wears a buccal fat pad on the deep side of the anterior edge of the temporal and chewing muscles. The buccal muscle is connected to the facial nerve branch to form a buccal plexus, which is distributed in the buccal mucosa, skin, buccal gums, periosteum and nearby mucosa in the mandibular molar area.

(2) posterior femur: large, mostly sensory nerves, branched by temporal ear nerve, lingual nerve, and inferior alveolar nerve. There are two auricular and temporal nerves, with the middle meningeal artery passing between the two. Travel backwards from the deep side of the external pterygoid muscles to the inner side of the mandible neck. Several branches are sent between the auricle and the mandibular condyle to the mandibular joint and the parotid gland. Facial nerve communication. Glingual nerve: It is located below the external pterygoid muscle, where the tympanic cord of the facial nerve is housed, and the parasympathetic secretory fibers of the facial nerve are introduced into the submandibular ganglia, and several branches are sent from the submandibular ganglia to the submandibular and sublingual glands. The lingual nerve goes down, before the inferior alveolar nerve, travels from the deep side of the external pterygoid muscle to between the internal pterygoid muscle and the mandibular branch, and enters the sublingual through the mandibular hyoid muscle, the styloid muscle, and the hyoid hyoid muscle. Area. Branches along the way to the ipsilateral sublingual mucosa, sublingual glands, lingual gums of the lingual side of the mandible, and two-thirds of the mucosa of the tongue. The inferior alveolar nerve enters the mandibular canal from the deep side of the external pterygoid muscle from the sphenoid mandibular ligament and the mandibular branch to the mandibular foramen. The mandibular hyoid muscle branch is issued at the point where it will enter the mandibular foramen and is distributed in this muscle and the forelimb of the digastric muscle. After the nerve enters the hole, it branches out to the mandibular molars, premolars and incisors along the way. When it reaches the palatine foramen, the palatine foramen is divided into palatal nerves, which are located under the deltoid muscle, and the branches are distributed on the gingival, gingival, mucosa and skin of the lip and buccal before the first premolar. The nerve of the same name is connected on the side. Connected to the mandibular nerve, there are two parasympathetic ganglia, one for the ear and the other for the submandibular. The ear segments are flat and oval-shaped, located slightly below the ovoid of the sphenoid bone. Several short fibers are used to connect the intramandibular branch of the mandibular nerve. The superficial petrosal nerve is used to connect the pharyngeal and facial nerves. The submandibular segment is small and fusiform, located between the hyoid hyoid muscle and the mandibular hyoid muscle, above the deep surface of the submandibular gland and below the lingual nerve. Several fibers are used to connect the lingual nerve and the facial nerve tympanum through the two fibers. Distributed in the oral mucosa, submandibular glands and their ducts, sublingual glands and tongue.
