Is there an artery in your bottom lip?

We found that the blood supply of the lower lip was derived from the facial artery and three dominant labial arteries: the inferior labial artery, the horizontal labiomental artery, and the vertical labiomental artery.

What is the superior labial artery?

Superior labial artery (old name: superior coronary artery) is one of the facial branches of the facial artery. It is bigger and more serpiginous than the inferior labial artery. It supplies the upper lip, including its labial glands, mucous membranes and muscles.

What’s the bit below your nose called?

philtrum
The human philtrum, bordered by ridges, also is known as the infranasal depression, but has no apparent function.

Where is the lingual artery?

The lingual artery passes between the middle constrictor of the pharynx and the hyoglossus muscles. [2] At the anterior border of the hyoglossus muscle, the lingual artery ascends to the tip of the tongue.

Are there arteries in the mouth?

What Is the Lingual Artery? The lingual artery supplies blood to the tongue as well as the floor of the mouth. It’s a major branch of the external carotid artery (blood vessels that supply blood to the brain, neck, and face).

Can you see veins on your lips?

Venous lakes are dilated ‘lake-like’ venules in the upper dermis typically seen on the lips or ears of elderly patients. These lesions are dark-blue to purple, soft, raised nodules, usually 2 to 10 mm in diameter.

What is the space between your lip and nose called?

The philtrum is the midline groove in the upper lip that runs from the top of the lip to the nose. The way the philtrum appears is determined genetically. In some syndromes this grove is shortened. The physical landmarks of the human face are very similar from one face to another.

What is the area between the lower lip and chin called?

Labiomental groove
Labiomental groove – Area that separates the lower lip and the chin.

What is the inferior labial artery?

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…

What is the depth of the superior labial artery?

The depth of the superior labial artery in the upper lip was 5.6 ± 0.13 mm, whereas the depth of the inferior labial artery in the lower lip was 5.2 ± 0.14 mm. Both arteries were more frequently located within the red lip: upper lip (83% vs 18.7%) and lower lip (86.2% vs 13.8%).

Where does the facial artery branched?

Results: The facial artery branched into the superior labial artery just above the labial commissure. This artery ran 4.5 mm deep along the upper lip between the oral mucosa and the orbicularis oris muscle just above the vermilion-mucosa junction to anastomose with the opposing artery.

Where is the arterial trunk of the lower lip?

The main arterial trunk coursed along the alveolar border within the plane between the orbicularis oris muscle and the lip depressors. From the arterial trunk emanated the inferior labial artery, which accompanied the mental nerve to the lower lip.
