Does mental nerve pass through mandibular foramen?
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.
