Artery Labial Superior

The superior labial artery is a large artery that is located superficially on the upper lip and provides blood supply to the mucous membrane of the lip and gums of the upper jaw. This artery is a branch of the ascending pharyngeal artery (a. pharyngea ascendens), which arises from the external carotid artery (A. carotis externa) in the transverse plane of the neck.

The labial artery inferior (a. Labialis inferior) is another large artery that passes through the lower lip and connects with the second branch of the superior labial artery at the anterior border of the lower lip. The arteries of the upper and lower lips have one common branch that connects their inner ends and is known as the superficial artery of the upper lip (v. facialis superficial).

In addition, the superficial branches of the labial arteries arise from them and supply the tissues of the upper and lower lips with cutaneous veins, which form vascular networks along the lip. These networks are formed by the system of superficial veins of the lip, which are basically groups of capillaries located parallel to the skin. The lower lip is supplied directly by the nutrient trunks of the lower lip, and each half of the upper lip is supplied by a double nutrient trunk of the upper lip.
