What does the superior labial artery supply?

The superior labial artery is a branch of the facial artery and is primarily responsible for supplying blood to the upper lip. This artery plays a crucial role in the vascularization of the tissue in this area, ensuring that the upper lip receives the necessary nutrients and oxygen-rich blood for healthy function and appearance.

In contrast, the other options pertain to different regions or structures that are not the primary function of the superior labial artery. The lower lip receives blood from the inferior labial artery, while the chin and the side of the nose have their own distinct blood supply sources. Understanding the specific role of the superior labial artery helps in recognizing its importance in facial aesthetics and health.
