Angular artery
Angular Artery
The Angular Artery (pronunciation: /ˈaŋɡjʊlər ˈɑːrtəri/) is a significant blood vessel in the human body. It is the terminal part of the Facial Artery, which is a branch of the External Carotid Artery.
Etymology
The term "Angular Artery" is derived from the Latin word "angulus," meaning angle, and the Greek word "arteria," meaning windpipe or artery. This name is given due to the artery's angular path on the face.
Function
The Angular Artery supplies blood to the upper and lower lips, the side of the nose, and the muscles and skin of the cheek. It also provides blood to the Lacrimal Sac, which is involved in tear production.
