Inferior Labial Artery
The Inferior Labial Artery (In-fe-ri-or La-bi-al Ar-te-ry) is a significant blood vessel in the human body that supplies blood to the lower lip.
Etymology
The term "Inferior Labial Artery" is derived from the Latin words 'inferior' meaning 'lower', 'labium' meaning 'lip', and 'arteria' meaning 'windpipe, artery'.
Anatomy
The Inferior Labial Artery is a branch of the Facial Artery, which is itself a branch of the External Carotid Artery. It arises near the angle of the mouth, and it passes upward and forward, crossing the lower border of the Depressor Labii Inferioris Muscle and runs along the edge of the lower lip between the Mucous Membrane and the Orbicularis Oris Muscle.
Function
The primary function of the Inferior Labial Artery is to supply blood to the lower lip. It also provides blood to the Mental Region of the face and the Labial Glands.
