Dural venous sinuses (English)

The cavernous sinus is a large venous plexus situated on either side of the sella turcica of the sphenoid bone. The cavernous sinus drains blood from the superior and inferior ophthalmic veins, superficial middle cerebral veins and sphenoparietal sinus. It is then drained by the superior and inferior petrosal sinuses that convey blood to the transverse sinuses and subsequent internal jugular vein.
