MENTAL NERVE

  

ORIGIN: Inferior alveolar nerve.

COURSE/DISTRIBUTION: This is a terminal branch of the inferior alveolar nerve which springs from that nerve at the mental foramen. It emerges under the depressor anguli oris and divides into three terminal branches. They are cutaneous branches to the skin of the chin.

BRANCHES:

bullet

Cutaneous branches

ROOT: Sensory root is from the sensory nuclei extending from the spinal nucleus of trigeminal from the substantia gelatinosa of the upper cervical region to the medulla, and the pontine nucleus which lies in the floor of the 4th ventricle. This extends to the midbrain mesencephalic nucleus of V.
