"The middle meningeal artery is the dominant supply of the cranial dura. It arises from the first part of the maxillary artery, a terminal branch of the external carotid artery. It enters the middle cranial fossa via the foramen spinosum. Here it gives off two basal branches—the petrosal branch and the cavernous branch—before dividing into anterior and posterior divisions 1:"

"anterior division: runs anterolaterally through the middle cranial fossa on the greater wing of sphenoid before coursing superiorly, often grooving the bone, and passes under the pterion before giving its terminal branches over the upper parietal bone"
"posterior division: runs horizontally posteriorly over the squamous part of the temporal bone to give rise to its terminal branches over the lower parietal bone"
