Posterior auricular vein
Posterior Auricular Vein
The Posterior Auricular Vein (Pronunciation: pos-teer-ee-or aw-rik-yuh-lar vein) is a significant vein in the human body, particularly in the anatomy of the ear.
Etymology
The term "Posterior Auricular Vein" is derived from Latin roots. "Posterior" means "behind", "Auricular" refers to "ear", and "Vein" is from the Latin "vena", meaning "blood vessel". Thus, the term refers to the blood vessel located behind the ear.
Anatomy
The Posterior Auricular Vein originates from the venous plexus on the side of the scalp and the back of the auricle, the visible part of the ear. It descends behind the ear, lying upon the mastoid process of the temporal bone, and joins the posterior division of the retromandibular vein to form the external jugular vein.
