Uberon definition : Mental nerve is a general somatic afferent (sensory) nerve which provides sensation
to the anterior aspects of the chin and lower lip as well as the buccal gingivae of
the mandibular anterior teeth and the premolars. It is a branch of the posterior trunk
of the inferior alveolar nerve, which is itself a branch of the mandibular division
of the trigeminal nerve (CN V). The nerve emerges at the mental foramen in the mandibula,
and divides beneath the Depressor anguli oris muscle into three branches: one descends
to the skin of the chin. two ascend to the skin and mucous membrane of the lower lip.
These branches communicate freely with the facial nerve.;
