Jul 19, 2024 · Dural venous sinuses are venous channels located intracranially between the two layers of the dura mater (endosteal layer and meningeal layer) and can be conceptualised as trapped epidural veins. Unlike other veins in the body, they run alone and not parallel to arteries.
Dural venous sinuses - Wikipedia
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.
