Cerebral arteries

The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain.

All three arteries send out arteries that perforate brain in the medial central portions prior to branching and bifurcating further.

The arteries are usually divided into different segments from 1–4 or 5 to denote how far the level of the branch with the lower numbers denoting vessels closer to the source artery.

Even though the arteries branching off these vessels retain some aspect of constancy in terms of size and position, a great amount of variety in topography, position, source and prominence nevertheless exists.
