The external jugular vein is a major blood vessel located in the neck. It is responsible for draining blood from the face, scalp, and neck, returning it to the heart. This vein runs superficially, meaning it is closer to the surface of the skin compared to other veins, making it easier to see and palpate in some individuals. The external jugular vein typically begins near the angle of the jaw and descends diagonally across the neck. It eventually empties into the subclavian vein, which is part of the larger venous system that carries deoxygenated blood back to the heart. Understanding the anatomy of the external jugular vein is important in medical procedures and assessments.
