The large sensory root of mandibular nerve emerges from the lateral part of the trigeminal ganglion and exits the cranial cavity through the foramen ovale. The motor root (Latin: radix motoria s. portio minor ), the small motor root of the trigeminal nerve , passes under the trigeminal ganglion and through the foramen ovale to unite with the ...
Both sensory and motor Pons: Three Parts: V 1 (ophthalmic nerve) is located in the superior orbital fissure V 2 (maxillary nerve) is located in the foramen rotundum. 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
The mandibular nerve (V 3) carries sensory information from the lower lip, the lower teeth and gums, the chin and jaw (except the angle of the jaw, which is supplied by C2-C3), parts of the external ear and parts of the meninges. The mandibular nerve carries touch-position and pain-temperature sensations from the mouth.
The trigeminal ganglion contains cell bodies of the pseudo-unipolar sensory neurons of the trigeminal nerve which extend their axons both distally/peripherally into the three divisions of the trigeminal nerve on the one end, and proximally/centrally to the brainstem on the other end; the trigeminal root extends from the trigeminal ganglion to the ventrolateral aspect of the pons.
It is in relation, laterally, with the trunk of the mandibular nerve at the point where the motor and sensory roots join; medially, with the cartilaginous part of the auditory tube, and the origin of the tensor veli palatini; posteriorly, with the middle meningeal artery. It surrounds the origin of the nerve to the medial pterygoid.
The inferior alveolar nerve (IAN) (also the inferior dental nerve) is a sensory [1] [contradictory] branch of the mandibular nerve (CN V 3) (which is itself the third branch of the trigeminal nerve (CN V)). The nerve provides sensory innervation to the lower/mandibular teeth and their corresponding gingiva as well as a small area of the face ...
The long ciliary nerves are 2-3 [1] nerves that arise from the nasociliary nerve (itself a branch of the ophthalmic branch (CN V 1) of the trigeminal nerve (CN V)).They enter the eyeball to provide sensory innervation to parts of the eye, and sympathetic visceral motor innervation to the dilator pupillae muscle.
It is a branch of the inferior alveolar nerve. It provides motor innervation the mylohyoid muscle, and the anterior belly of the digastric muscle. It provides sensory innervation to part of the submental area, and sometimes also the mandibular (lower) molar teeth, requiring local anaesthesia for some oral procedures.
