The inferior labial artery passes anteriorly beneath the depressor anguli oris muscle penetrating the orbicularis oris. It runs along the margin of the lower lip between the orbicularis oris muscle and the mucous membrane of the lip. The inferior labial artery forms anastomoses with the opposite inferior labial artery and with the mental artery - a branch of the inferior alveolar artery.
