Mandibular nerve
Mandibular Nerve
The Mandibular Nerve (/mænˈdɪbjʊlər nɜːrv/; from Latin mandibula, "jawbone") is the largest of the three divisions of the Trigeminal Nerve, which is the fifth cranial nerve (CN V). It supplies the lower face, lower teeth, part of the tongue, and some muscles of mastication.
Anatomy
The Mandibular Nerve originates from the Trigeminal Ganglion, a collection of nerve cell bodies that is located within the Meckel's Cave. It then passes through the Foramen Ovale, a hole in the base of the skull, to reach the infratemporal fossa.
Branches
The Mandibular Nerve gives off several branches, including:
- Buccal Nerve: Supplies the skin and mucous membrane of the cheek.
- Lingual Nerve: Supplies the anterior two-thirds of the tongue.
- Inferior Alveolar Nerve: Supplies the lower teeth.
- Auriculotemporal Nerve: Supplies the skin in front of the ear and the skin of the temporal region.
Clinical Significance
Damage to the Mandibular Nerve can result in loss of sensation in the areas it supplies, difficulty in chewing, and other symptoms. It can be affected by various conditions, such as Trigeminal Neuralgia, a chronic pain condition that affects the Trigeminal Nerve.
