mandibular nerveAbbreviation: CN V3
The major sensory branches are the auriculotemporal, lingual, and inferior alveolar nerves, which innervate the lower teeth and gingivae and the skin of the lower lip, chin, and jaw up into the "sideburn area" in front of the ear.
The major motor branches are the lateral pterygoid, masseteric, deep temporal, and buccal nerves, which innervate the muscles of mastication (lateral and medial pterygoids, masseter, and temporalis).
The mandibular nerve leaves the skull via the foramen ovale.
