Inferior alveolar nerve

The inferior alveolar nerve ( " nerve of the mandibular subjects" ) is a branch of the mandibular nerve ( " mandibular nerve" ), which in turn is a branch of the fifth cranial nerve is ( trigeminal nerve ).

The inferior alveolar nerve passes through the foramen of the mandible ( lower jaw hole ) in the lower jaw bone. Here he runs in a bony canal ( mandibular canal ) chin upward and are each branches ( Rami alveolar ) to the teeth of the lower jaw from.

The terminal branch of the inferior alveolar nerve exits the mandible at the mental foramen. This is the mental ( " chin nerve" ) designated and supplies the skin of the chin and lower lip nerve.

Both mandibular foramen and mental foramen nerve block anesthesia of the nerves to eliminate pain during dental procedures is possible.
