Dural Sinus Anatomy - Introduction of dural venous sinuses. The dural venous sinuses are spaces between the periosteal and meningeal layers of dura mater, which are lined by endothelial cells. The intracranial venous system, most specifically, the dural venous sinuses, demonstrates considerable anatomic variation. The superior petrosal sinus is a part of the dural venous sinus system that drains venous blood and cerebrospinal fluid circulating within the cranial cavity. The dura mater is composed of two layers:
The periosteal/endosteal layer and the meningeal layer. All the dural venous sinuses ultimately drain into the. The extra sinuses go under a broad term of “dural sinus” — the best thing to do, as always, is to simply describe what exists — for example “left parietal dural sinus draining into the superior sagittal sinus”. Developmentally, these sinuses emerge as venous plexuses and exhibit a variable degree of plexiform arrangement, rather than the single luminal structure (tubbs et al., 2011). The dural venous sinus system empties into the internal jugular vein and further flows into the cardiovascular circulation via the superior vena cava. Learn this topic now at kenhub! The dural venous sinuses (dvs), in general, are frequently asymmetrical and display far more anatomical variations than arterial systems.

Each cavernous sinus has a close anatomical relationship with several key structures in the head. They collect blood from different venous systems, drain into the internal jugular veins, and are resistant to compression due.
