Into which vein does the common facial vein, formed by the anterior division and the facial vein, eventually drain?

  1. Brachiocephalic vein

  2. External jugular vein

  3. Internal jugular vein

  4. Subclavian vein

The correct answer is: Internal jugular vein

The common facial vein, formed by the anterior division and the facial vein, eventually drains into the internal jugular vein. The internal jugular vein is a major vein that collects blood from the brain and face, and then transports it to the heart. The other options listed, such as the brachiocephalic vein, external jugular vein, and subclavian vein, are not part of the pathway for drainage of the common facial vein, making them incorrect choices. Additionally, the internal jugular vein is the largest vein in the neck and can be easily identified and accessed for medical procedures, making it an important structure to be familiar with.
