Which sinus is located at the junction of the falx cerebri and tentorium cerebri?

Explanation:
The straight sinus sits exactly at the junction where the falx cerebri meets the tentorium cerebelli. It’s formed by the union of the inferior sagittal sinus and the great cerebral vein (vein of Galen) and then runs posteriorly to drain into the confluence of sinuses. The other sinuses describe different paths: the superior sagittal sinus travels along the top edge of the falx, the inferior sagittal sinus runs along the lower edge and feeds into the straight sinus, and the transverse sinuses extend laterally from the confluence.
