The straight sinus (tentorial sinus) is situated at the line of junction of the falx cerebri with the tentorium cerebelli.
It is triangular in section, increases in size as it proceeds backward, and runs downward and backward from the end of the inferior sagittal sinusand continues as the left transverse sinus, but may deviate to the right.
Its terminal part communicates by a cross branch with the confluence of the sinuses. Besides the inferior sagittal sinus, it receives the great cerebral vein (great vein of Galen) and the superior cerebellar veins.
A few transverse bands cross its interior.
