Description

The mental nerve (n. mentalis) emerges at the mental foramen, and divides beneath the Triangularis muscle into three branches; one descends to the skin of the chin (Mental branches), and two ascend to the skin and mucous membrane of the lower lip (gingival branches and labial branches); these branches communicate freely with the facial nerve.
