Meninges of the brain (superior view) (English)

The most superficial of the meninges is the dura mater, in the middle is the arachnoid mater and the deepest is the pia mater. One of the dural venous sinuses, the superior sagittal sinus, is located along the midline and drains into the confluence of sinuses. On either side of the superior sagittal sinus are lateral expansions within the dura mater referred to as the lateral venous lacunae. The middle meningeal artery, a branch of the maxillary artery, provides the dominant supply of the cranial dura mater. The superior cerebral veins drain the superolateral/medial portion of each cerebral hemisphere.
