In neuroanatomy, the mandibular nerve (V 3) is the largest of the three divisions of the trigeminal nerve, the fifth cranial nerve (CN V). Unlike the other divisions of the trigeminal nerve ( ophthalmic nerve , maxillary nerve ) which contain only afferent fibers , the mandibular nerve contains both afferent and efferent fibers .
The marginal mandibular branch of the facial nerve is found superficial to the facial artery and (anterior) facial vein. Thus the facial artery can be used as an important landmark in locating the marginal mandibular nerve during surgical procedures. [2]
The mandibular nerve is one of three branches of the trigeminal nerve, and the only one having motor innervation.One branch of it, the inferior alveolar nerve, as well as the inferior alveolar artery, enter the foramen traveling through the body in the mandibular canal and exit at the mental foramen on the anterior mandible at which point the nerve is known as the mental nerve.
The risk of nerve injury in relation to mandibular dental implants is not known but it is a recognised risk requiring the patient to be warned. [10] If an injury occurs urgent treatment is required. The risk nerve injury in relation deep dental injections has a risk of injury in approximately 1:14,000 with 25% of these remaining persistent.
The meningeal branch of the mandibular nerve (also known as the nervus spinosus) [1] is a sensory branch of the mandibular nerve (CN V3) that enters the middle cranial fossa through either the foramen spinosum or foramen ovale to innervate the meninges of this fossa as well as the mastoid air cells.

The mental nerve is a branch of the posterior trunk of the inferior alveolar nerve. This is a branch of the mandibular nerve (CN V 3), itself a branch of the trigeminal nerve (CN V). [1] It emerges from the mental foramen in the mandible. [2] It divides into three branches beneath the depressor anguli oris muscle.
Unlike most of the other facial muscles, which are innervated by the facial nerve (or CN VII), the muscles of mastication are innervated by the trigeminal nerve (or CN V). More specifically, they are innervated by the mandibular branch, or V 3. The mandibular nerve is both sensory and motor.
The masseteric nerve is a nerve of the face. It is a branch of the mandibular nerve (CN V 3). It passes through the mandibular notch to reach masseter muscle. It provides motor innervation the masseter muscle, and sensory innervation to the temporomandibular joint.
