Definition

Noun: 1. A short vein in the face: The angular vein is a specific, short blood vessel located near the inner corner of the eye. It is formed by the union of two other veins (the supraorbital and supratrochlear veins) and continues downward as the facial vein.

Usage

The term "angular vein" is used exclusively in anatomical and medical contexts to describe this specific vascular structure. * It is typically used with definite articles or possessive determiners (e.g., the angular vein, its angular vein). * It functions as a subject or object in sentences describing facial anatomy, surgical procedures, or clinical conditions.

Examples
