Characteristics Of Dural Venous Sinuses.

Veins are characterized by a larger caliber than the cerebral arteries, have thin walls lacking muscular tissue and valves. It is a single or paired midline venous structure, either arising from the torcular herophili or the medial transverse sinus. Superior blood stream (vault) :superior sagittal sinus, inferior sagittal sinus.
