(a) Inferior sagittal sinus, inferior to flax cerebri
(b) Superior sagittal sinus, superior to falx cerebri
(c) Straight sinus, inferior to falx cerebri
(d) Transverse sinus, posterior to falx cerebri

Answer 1

The superior sagittal sinus is located superior to the falx cerebri and is responsible for draining blood from the superior surface of the cerebrum.

Step-by-step explanation:

The student is asking about the venous drainage of the brain in relation to the falx cerebri. The superior sagittal sinus is the enlarged vein located midsagittally between the meningeal and periosteal layers of the dura mater within the falx cerebri. It receives most of the blood drained from the superior surface of the cerebrum and leads to the inferior jugular vein and the vertebral vein. Therefore, the correct answer to the question is (b) Superior sagittal sinus, superior to falx cerebri.
