・From:
Sigmoid sinus
・To:
Angulus venosus
・Artery:
Internal carotid artery
Common carotid artery
・Course:
It is continuous from the sigmoid sinus at the jugular foramen, and descends along the lateral side of the Internal carotid artery at first, then along that of the Common carotid artery.
It joins the Subclavian vein at the angulus venosus, which continues into the Brachiocephalic vein.
Its origin and the terminal are dilated.
These diltations are called the superior bulb and the inferior bulb respectively.
