The artery extends from the sphenoidal segment of the MCA via the inferior surface of the operculum and supplies the polar and anterior lateral portions of the temporal lobe.

The blood supply to the brain divides into an anterior and posterior circulation. The vessel can be identified in 52 of normal. The middle cerebral arteries supplying the brain are not considered part of the circle of Willis.
