internal jugular!
The internal jugular vein is formed from the sigmoid sinus (after receiving the lesser petrosal sinus) just after passing through the jugular foramen to become the internal jugular vein.
In humans there is one external and one internal jugular vein. The internal jugular vein is much larger (about twice the diameter) of the external jugular. In the cat there are a pair of each vein but the external jugular vein is about twce as large as the internal. (Opposite of humans.)
