Where do the external and internal jugular veins join?
The veins that drain the brain They are the main path for deoxygenated blood returning from the cranium back to the heart. The external jugular veins empty into the subclavian veins; the internal jugular veins join with the subclavian veins to form the brachiocephalic veins, which join to form the superior vena cava.
Is anterior jugular vein and internal jugular vein same?
Just above the sternum the two anterior jugular veins communicate by a transverse trunk, the venous jugular arch, which receive tributaries from the inferior thyroid veins; each also communicates with the internal jugular. There are no valves in this vein.
Where does the external jugular vein arise from?

What does anterior jugular vein mean?
The anterior jugular vein is a paired blood vessel that drains the anterior aspect of the neck. It emerges from the confluence of the superficial submandibular veins beneath the chin and drains into the external jugular vein. Less frequently, it may drain directly into the subclavian vein.
What happens if you cut the external jugular vein?

What is jugular vein and its functions?
Jugular vein, any of several veins of the neck that drain blood from the brain, face, and neck, returning it to the heart via the superior vena cava. The main vessels are the external jugular vein and the interior jugular vein. The external jugular vein receives blood from the neck, the outside of the cranium, and the deep tissues of the face and empties into the subclavian veins (continuations of the principal veins of the arms or forelimbs).
What do the internal and external jugular veins do?
There are two jugular veins on each side of the neck, known as the external and internal jugulars. The external one lies close to the surface and carries blood from the outside parts of the head and neck to the heart. The internal one lies deeper and carries blood from the deeper tissues of the neck and from the interior of the skull.
