Angular vein
Angular Vein
The Angular Vein (pronunciation: an-gyuh-lar vayn) is a significant vein in the human body, specifically located in the facial region.
Etymology
The term "Angular" is derived from the Latin word "Angulus", meaning "angle", and the term "Vein" is derived from the Latin word "Vena", meaning "blood vessel". The Angular Vein is so named due to its angular position on the face.
Anatomy
The Angular Vein is the terminal part of the Facial Vein, and it is located at the angle of the eye, near the bridge of the nose. It runs obliquely downward, from the medial angle of the eye, along the side of the nose, and ends at the lower part of the nose where it becomes the Anterior Facial Vein.
Function
The primary function of the Angular Vein is to drain blood from the superior part of the face, including the forehead, eyelids, and nose, back towards the heart. It also communicates with the Superior Ophthalmic Vein and the Inferior Ophthalmic Vein, aiding in the drainage of the orbit.
