Inferior labial artery
The inferior labial artery (inferior labial branch of facial artery) arises near the angle of the mouth as a branch of the facial artery; it passes upward and forward beneath the triangularis and, penetrating the orbicularis oris, runs in a tortuous course along the edge of the lower lip between this muscle and the mucous membrane.
