A dural venous sinus, in human anatomy, is any of the channels of a branching complex sinus network that lies between layers of the dura mater, the outermost covering of the brain, and functions to collect oxygen-depleted blood. Unlike veins, these sinuses possess no muscular coat.
8 sie 2023 · There are seven major dural venous sinuses located within the cranial cavity, specifically between the periosteal and meningeal layer of the dura mater: superior sagittal, inferior sagittal, straight, transverse, sigmoid, cavernous, and superior petrosal sinuses.
The dural venous sinuses (also termed dural sinuses, cerebral sinuses, or cranial sinuses) are venous channels found between the periosteal and meningeal layers of dura mater in the brain.
