The arterial supply to the lower lip is vital in oral surgery and dentistry. The scientific term for this blood vessel is "Arteria Labialis Inferior." However, it is also known as the inferior labial artery or labial branch of the facial artery. In some literature, it is mentioned as inferior coronary artery of the lips. It arises from the external carotid artery and supplies the muscles and tissues of the lower lip. Additionally, it contributes to blood supply to the chin, mentalis muscle, and lower gums. Variations in the naming of this artery may depend on anatomical differences or regional preference.
