Blood vessels · Latin: Arteria cerebri posterior

The posterior cerebral artery (PCA) is one of a pair of cerebral arteries that supply oxygenated blood to the occipital lobe, part of the back of the human brain.

The two arteries originate from the distal end of the basilar artery, where it bifurcates into the left and right posterior cerebral arteries.

These anastomose with the middle cerebral arteries and internal carotid arteries via the posterior communicating arteries.
