It detaches the linguo facial trunk, occipital artery and a common stem for the caudal auricular and the superficial temporal arteries, then the parent vessel continues as the maxillary artery. On the surface of the face,the facial artery gives off the inferior labial artery then continues as the superior labial artery.
