External Jugular Vein
The External Jugular Vein (Pronunciation: Ex-ter-nal Ju-gu-lar Vain) is a significant vein in the human body that drains blood from the face, scalp, and superficial parts of the neck.
Etymology
The term "External Jugular Vein" is derived from the Latin words "externus" meaning "outside", "jugulum" meaning "throat", and "vena" meaning "vein".
Anatomy
The External Jugular Vein begins near the angle of the mandible (jawbone) and runs down the neck, superficial to the sternocleidomastoid muscle. It drains into the subclavian vein, which eventually leads to the heart.
