<br />
The '''Posterior Auricular Vein''' is a vein that drains the scalp posterior to the [[auricle (anatomy)|auricle]] and the back of the auricle itself. It is a part of the [[human circulatory system]] and plays a crucial role in the venous drainage of the head and neck.<br />
<br />
==Structure==<br />
The Posterior Auricular Vein arises from the [[pinna (anatomy)|pinna]] of the ear and the scalp posterior to the auricle. It descends behind the auricle, where it joins the [[posterior division]] of the [[superficial temporal vein]] to form the [[external jugular vein]].<br />
<br />
==Function==<br />
The primary function of the Posterior Auricular Vein is to drain blood from the region behind the ear and the outer part of the ear. It then carries this deoxygenated blood towards the heart, contributing to the overall circulation of blood in the body.<br />
<br />
==Clinical significance==<br />
Knowledge of the Posterior Auricular Vein is important in several medical procedures, including [[cannulation]], [[venipuncture]], and in surgeries involving the ear or surrounding areas.<br />
