superior sagittal sinus
n.
An unpaired dural sinus in the sagittal groove.

superior sagittal sinus,
one of the six venous channels in the posterior of the dura mater that drains blood from the brain into the internal jugular vein. It has no valves. The superior sagittal sinus receives the superior cerebral veins, veins from the diploë and near the posterior extremity of the sagittal suture, the anastomosing emissary veins from the pericranium, and the veins from the dura mater. It also anastomoses with veins of the nose, the scalp, and the diploë. Compare inferior sagittal sinus, straight sinus, transverse sinus.
