From Wikipedia, the free encyclopedia.
The mandibular nerve is the third branch (V3) of the trigeminal nerve. It exits the cranial fossa (at the base of the skull) through the foramen ovale.
It conveys sensation from the lower teeth, mandible as well as the lower lip, cheek and chin. It also supplies part of the tongue as well as the inside of the cheek (the buccal mucosa).
It runs into the mandible via the mandibular foramen where it becomes the inferior alveolar nerve. The inferior alveolar nerve carries sensation from the teeth of the lower jaw and their surrounding soft tissue.
