A sphenoparietal sinus is situated under each lesser wing of the sphenoid bone near the posterior edge of this bone, [2] between the anterior cranial fossa and middle cranial fossa. [ citation needed ] It terminates by draining into the anterior part of the cavernous sinus .
The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere.It runs along the lateral sulcus [1] to empty into either the cavernous sinus, [1] [2] or sphenoparietal sinus. [1]

The frontal, which opens into the supraorbital vein and the superior sagittal sinus. The anterior temporal, which is confined chiefly to the frontal bone, and opens into the sphenoparietal sinus and into one of the deep temporal veins, through an aperture in the great wing of the sphenoid.
The cavernous sinus receives blood from: [2] Superior and inferior ophthalmic veins [3]; Sphenoparietal sinus [3]; Superficial middle cerebral veins [3]; Inferior cerebral veins; Blood leaves the sinus via superior and inferior petrosal sinuses as well as via the emissary veins through the foramina of the skull (mostly through foramen ovale).

The walls of the dural venous sinuses are composed of dura mater lined with endothelium, a specialized layer of flattened cells found in blood and lymph vessels.They differ from other blood vessels in that they lack a full set of vessel layers (e.g. tunica media) characteristic of arteries and veins.
