Posterior auricular vein
The posterior auricular vein is the name for a vein that is made out of the venous tributaries that are situated behind the ear. The auricular veins combine with the posterior facial vein and in turn create the external jugular vein. This occurs when the vein travels behind the auricula and then merges with the back portion of the posterior facial vein. The external jugular vein describes the vein that is the recipient for the majority of the blood of the cranium's exterior portion. The vein also receives blood from the deepest sections of the face. The posterior auricular vein starts out on one side of the head. It starts within a plexus, which is an aspect of the central nervous system. The plexus is capable of communicating with the tributaries of both the superficial temporal vein and occipital vein. The vein is a recipient of the stylomastoid vein, which is responsible for draining out the tympanic cavity into the retromandibular vein.
