 Dural veins (superior sagittal sinus at top, labeled "sin. sagittalis sup." for Latin sinus sagittalis superior) | |
 Superior sagittal sinus laid open after removal of the skull cap. The chordae Willisii are clearly seen. The venous lacunæ are also well shown; from two of them probes are passed into the superior sagittal sinus. | |

| Anatomical terminology | |
The superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired dural venous sinus lying along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of the anterior cerebral hemispheres to the confluence of sinuses. Cerebrospinal fluid drains through arachnoid granulations into the superior sagittal sinus and is returned to the venous circulation.
