The innominate veins are also known
as the "brachiocephalic
veins".
The term innominate vein can
refer to either of two veins, one of which is located on each side of
the neck and is formed by the junction of the external jugular and the
subclavian veins (on the appropriate side of the body).
The two innominate veins join to form the superior
vena cava which drains blood from the
head, neck, thorax, and arms.

the inferior vena cava relative to the positions of other major veins
and arteries, visit the page about Systemic
