What is the Retromandibular vein?

Subsequently, one may also ask, what does the facial vein drain into?

Facial vein. It lies behind the facial artery and follows a less tortuous course. It receives blood from the external palatine vein before it either joins the anterior branch of the retromandibular vein to form the common facial vein, or drains directly into the internal jugular vein.

Furthermore, what forms the common facial vein? The facial vein usually unites with the anterior branch of the retromandibular vein to form the common facial vein, which crosses the external carotid artery and enters the internal jugular vein at a variable point below the hyoid bone.

Besides, where is the maxillary vein located?

The maxillary veins consist of the main maxillary blood vessel and its extensions. This group of veins is located in the head. It is accompanied by the maxillary artery that runs alongside the vein. They are identified as one of the major groups of deep veins in the head.

Where does the superficial temporal vein drain?

The superficial temporal vein descends along the auricular anterior surface, then it joins with the maxillary vein at the level of mandibular neck and further continues as the retromandibular vein which drains into the internal or external jugular vein.
