The straight sinus (tentorial sinus) is situated along the junction of the falx cerebri and the tentorium cerebelli.

It forms from the confluence of the inferior sagittal sinus and great cerebral vein (great vein of Galen). In cross-section it is triangular, contains a few transverse bands across its interior, and increases in size as it proceeds backward. It receives the superior cerebellar veins.

The terminal part of the straight sinus drains into the confluence of the sinuses.
