The inferior cortical branch is one of the two terminal branches of the middle cerebral artery, the other being the superior terminal branch. It is also known as the inferior terminal trunk of the middle cerebral artery, or the inferior cortical branch of the middle cerebral artery.
From its origin, near the anterior part of the lateral sulcus, it travels posterosuperiorly along the lateral sulcus, inferior to the superior terminal branch. Along its course, the inferior terminal branch of the middle cerebral artery gives off branches; these include the anterior temporal, middle temporal posterior temporal branches, the anterior parietal and posterior parietal arteries, as well as the branch to the angular gyrus.
Overall, the inferior terminal branch of the middle cerebral artery and its branches provide an arterial supply to the temporal and parietal lobes, and the angular gyrus.
