The straight sinus drains blood toward which dural venous sinuses?

Explanation:
The straight sinus collects blood from deep cerebral structures by receiving the inferior sagittal sinus and the great vein of Galen, then runs toward the back of the skull along the falx cerebri. Its immediate drainage destination is the confluence of sinuses, located near the internal occipital protuberance. From there, venous blood flows into the transverse sinuses and on to the sigmoid sinuses and eventually the internal jugular veins. So, the straight sinus drains toward the confluence of sinuses first, with the transverse sinuses acting downstream in the pathway.
