Cerebral arteries

Cerebral arteries describe three main pairs of arteries and their branches, which irrigate the cerebrum of the brain. The three main arteries consist of the:

Both the ACA and MCA originate from the cerebral portion of internal carotid artery, while PCA branches from the intersection of the posterior communicating artery and the anterior portion of the basilar artery. The three pairs of arteries are linked via the anterior communicating artery and the posterior communicating arteries. All three arteries send out arteries that perforate brain in the medial central portions prior to branching and bifurcating further.
