Figure 2b. Three dimensional view of the dural anatomy. The meningeal arteries (MA) and veins (MV) are superficially located, while the dural venous plexus (DP) is located within the inner portion of the dura (intradural). The dural plexus is particularly dense parasagittally, where it connects to the sagittal sinus independently of the cortical BV. From Mack, et. al. 2009. BV, bridging vein; MA, meningeal artery; MV, meningeal vein; PA, penetrating arteriole extending to inner dural plexus; DP dural plexus; SS, superior sagittal sinus.
