MSH: The long large endothelium-lined venous channel on the top outer surface of the brain. It receives blood from a vein in the nasal cavity, runs backwards, and gradually increases in size as blood drains from veins of the brain and the DURA MATER. Near the lower back of the CRANIUM, the superior sagittal sinus deviates to one side (usually the right) and continues on as one of the TRANSVERSE SINUSES.,NCI: An intracranial venous sinus that lies in a superior and midline location above the interhemispheric fissure along the superior border of the falx cerebri of the brain. The sinus receives blood from the cerebral veins and drains posteriorly into the lateral sinuses of the brain, which in turn drain into the internal jugular veins.
