common iliac artery in dogs

The common iliac arteries are two large arteries, about 4cm long in adults but more than a centimetre in diameter, that originate from the aortic bifurcation. The arteries run inferolaterally, along the medial border of the psoas muscles to the pelvic brim, where they bifurcate into the external iliac artery and internal iliac artery. The common iliac artery, and all of its branches, exist as paired structures (that is to say, there is one on the left side and one on the right). The distribution of the common iliac artery is basically the pelvis and lower limb on the corresponding side. Both common iliac arteries are accompanied along their course by common iliac veins.

Where the common iliac artery is

It sits within the cardiovascular system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the common iliac artery connects to

The atlas records 5 typed relationships for it, across 3 kinds of connection. a kind of abdominal aorta artery and iliac artery.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the common iliac artery. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.
