The inferior sagittal sinus drains blood from which brain regions into the straight sinus?

Explanation:
The Inferior sagittal sinus collects blood from the deep, medial areas of the cerebral hemispheres—the parts served by the deep venous system, such as internal cerebral veins and related deep structures around the corpus callosum. It runs along the inferior edge of the falx cerebri and joins with the great cerebral vein (vein of Galen) to form the straight sinus. From there, venous blood drains toward the confluence of sinuses and onward to the other venous pathways. So, the drainage described is specifically from the deep and medial aspects of the cerebral hemispheres.
