The arterial supply to the dura mater (Fig. 8.33) travels in the outer periosteal layer of the dura and consists of: anterior meningeal arteries in the anterior cranial fossa, the middle and accessory meningeal arteries in the middle cranial fossa, and the posterior meningeal artery and other meningeal branches in the posterior cranial fossa.
All are small arteries except for the middle meningeal artery, which is much larger and supplies the greatest part of the dura.
