ANGULAR ARTERY Meaning and
Definition
-
The angular artery is a term used in human anatomy to refer to a specific blood vessel located in the head and face region. It is a branch of the facial artery, which itself is a branch of the external carotid artery. The angular artery is responsible for supplying blood to various structures in the face, including the nose, eyelids, and lips.
The angular artery is named as such due to its location at the corner or angle of the eye. It courses along the side of the nose, where it gives off several branches to ensure proper blood supply to the aforementioned facial structures. These branches include the dorsal nasal artery, which supplies blood to the upper region of the nose, and the lateral nasal artery, which supplies blood to the lower region of the nose.
In addition to its vital role in providing oxygenated blood to the face, the angular artery also plays a significant role in facial expressions. This is because it runs in close proximity to various muscles responsible for facial movements, allowing for the necessary nutrients and oxygen to reach these muscles.
Due to its location, the angular artery may be susceptible to injury in certain medical procedures or trauma. In such cases, prompt medical attention is required to prevent severe bleeding or other complications.

Etymology of ANGULAR ARTERY
The word "angular artery" consists of two elements: "angular" and "artery".
1. "Angular" comes from the Latin word "angulus", meaning "corner" or "angle". In anatomy, "angular" generally refers to something related to angles or corners.
2. "Artery" comes from the Latin word "arteria", which was derived from the Greek word "arteria" meaning "windpipe" or "artery". The Greek word was used because arteries were thought to be air-filled tubes carrying air through the body rather than blood vessels. Eventually, the term "artery" specifically came to refer to the blood vessels that carry oxygenated blood away from the heart.
Therefore, the word "angular artery" refers to an artery associated with an angle or corner, such as the angular artery found near the angle of the jaw, typically supplying blood to the facial region.
