trifurcations and the posterior cerebral arteries.

human anatomy, the posterior communicating artery is a one of a pair of right-sided and left-sided blood vessels in the circle of Willis. It connects the three cerebral arteries of the same side. Anteriorly, it is one portion of the terminal trifurcation of the internal carotid artery. The anterior cerebral arteryand the middle cerebral arteryare the other two branches of the trifurcation. Posteriorly, it communicates with the posterior cerebral artery.
Aneurysms of the posterior communicating artery are the second most common circle of Willis
