Examples
- The internal jugular vein originates as a continuation of the sigmoid sinus of the dura mater in the jugular foramen and then descends through the neck.
- It collects blood from the posterior of the head and neck, as well as from the anterior surfaces via connections with the anterior jugular veins, then joins the subclavian vein.
- A key anatomic landmark for the internal jugular vein is its junction with the subclavian vein to form the brachiocephalic vein.
- The junction with the subclavian vein generally varies slightly in location and serves as an essential spot in understanding internal jugular vein anatomy.
- The internal jugular vein combines with the subclavian vein behind the sternoclavicular joint to form the brachiocephalic vein or the innominate vein.
