Quick Facts

The artery of precentral sulcus (aka precentral sulcal artery, or pre-Rolandic artery) arises from the superior terminal branch of the middle cerebral artery.

From its origin, it travels superiorly, along the lateral surface of the cerebral hemisphere, towards the precentral sulcus, which it also travels along.

It provides an arterial supply to the precentral sulcus and the areas of the cerebral cortex that lie adjacent to it.
