Straight Sinus

The "straight sinus" is a channel for venous blood returning to the heart. It is located in the brain stem, where it opens into the transverse sinus on the side opposite in which the superior sagittal sinus terminates. The straight sinus receives blood from the inferior sagittal sinus, from the great cerebral vein and from the superior cerebellar veins. A few fibrous bands cross below it.
