What is the superior longitudinal sinus?

The superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired area along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of anterior cerebral hemispheres to the confluence of sinuses.

What is the function of superior sagittal sinus?

The purpose of the superior sagittal sinus is to carry waste and fluids away from the brain as veins do throughout the rest of the body.

Does CSF flow through superior sagittal sinus?

CSF then flows into the subarachnoid space through the foramina of Luschka (there are two of these) and the foramen of Magendie (only one of these). Absorption of the CSF into the blood stream takes place in the superior sagittal sinus through structures called arachnoid villi .
