High Quality Content by WIKIPEDIA articles! The superior sagittal sinus (also known as the superior longitudinal sinus), within a human cranium, is an area above/behind the brain, which allows blood veins to span the area, from the top of the head towards the back. It is believed that the cerebrospinal fluid drains through the arachnoid granulations into the dural venous sinuses of the superior sagittal sinus.Commencing at the foramen cecum, through which it receives a vein from the nasal cavity, it runs from anterior to posterior, grooving the inner surface of the frontal, the adjacent margins of the two parietal lobes, and the superior division of the cruciate eminence of the occipital lobe; near the internal occipital protuberance, it deviates to either side (usually the right), and is continued as the corresponding transverse sinus.
