Which artery supplies the lower region of the face and nose?

The correct answer is that the artery supplying the lower region of the face and nose is the facial artery. This artery branches off from the external carotid artery and runs along the side of the face, providing blood to various structures, including the lips, lower jaw, and nose.

Understanding the role of the facial artery is important in esthetics because it is directly involved in facial procedures, surgeries, and cosmetic treatments. This artery is responsible for the vascularization of the areas of the face where many esthetic interventions take place, such as dermal fillers or other injectables, making it essential knowledge for practitioners in the field.

In the context of the other provided choices, the external carotid artery is a major artery that supplies blood to the face and neck but is more general and does not directly indicate the specific lower region. The internal maxillary artery also branches from the external carotid, but it primarily supplies deeper structures within the face and does not focus on the outer lower regions. The term "external maxillary" is not a recognized primary artery in this context, hence not applicable in anatomical references.

So, recognizing the distinct function of the facial artery in cosmetic applications is key to understanding the question's focus on the vascularization of the
