Posterior Auricular Artery

The posterior auricular artery is an oxygen-rich blood vessel which originates from the external carotid artery and gives off the muscular, posterior tympanic, auricular, occipital, and stylomastoid branches. The posterior auricular artery supplies oxygenated blood to the part of the scalp lying behind the external ear (auricle) and the external ear itself.
