The Mandibular foramen is an opening on the internal surface of the ramus (posterior and perpendicularly oriented part of the mandible) for divisions of the mandibular vessels and nerve to pass.

The mandibular nerve is one of three branches of the trigeminal nerve (CN V) and the only branch with motor innervation.
The inferior alveolar nerve and inferior alveolar artery enter the foramen traveling through the body and exit at the mental foramen on the anterior mandible at which point the nerve is known as the mental nerve.
These nerves provide sensory innervation to the lower teeth, as well as the lower lip and some skin on the lower face.
There are two distinct anatomies to its rim.
 Articulation of the mandible. Medial aspect. |
