The mandibular nerve immediately passes between tensor veli palatini, which is medial, and lateral pterygoid, which is lateral, and gives off a meningeal branch (nervus spinosus) and the nerve to medial pterygoid from its medial side. The nerve then divides into a small anterior division and a large posterior division.
V 3 (mandibular nerve) is located in the foramen ovale. Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication. VI Abducens: Mainly motor Nuclei lying under the floor of the fourth ventricle Pons. Located in the superior orbital fissure. Innervates the lateral rectus, which abducts the eye. VII Facial
Inferior head: lateral pterygoid plate of sphenoid bone Mandible; temporo-mandibular joint Medial pterygoid: Elevates, protracts, laterally moves mandible (closes mouth; pushes lower jaw out/forward; moves lower jaw side-to-side) Deep head: medial surface of lateral pterygoid plate and palatine bone. Superficial head: tuberosity of maxilla
The mandibular nerve, the third branch of the trigeminal nerve (CN V 3), also known as the "inferior maxillary nerve", enters infratemporal fossa from the middle cranial fossa through the foramen ovale of the sphenoid bone. [3] The mandibular nerve gives off four nerves to the four muscles of mastication in the infratemporal

The lateral pterygoid muscle, auriculotemporal nerve, and the maxillary artery and maxillary vein are situated laterally to the SML (the vessels and nerve coursing betwixt the SML, and the neck of the mandibular condyle [1] [3]). [1] The chorda tympani nerve is situated medially to the SML [1] near its upper end. [citation needed]
The auriculotemporal nerve is a sensory branch of the mandibular nerve (CN V 3) that runs with the superficial temporal artery and vein, and provides sensory innervation to parts of the external ear, scalp, and temporomandibular joint. The nerve also conveys post-ganglionic parasympathetic fibres from the otic ganglion to the parotid gland. [1]
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.
