Which cerebral venous sinuses drain into the internal jugular vein (IJV)?

The correct response identifies the anatomical pathways that facilitate the drainage of venous blood from the brain to the internal jugular vein, specifically highlighting the role of the sigmoid sinus and the inferior petrosal sinus in this process.

The sigmoid sinus is situated in the posterior cranial fossa and serves as a crucial conduit for venous blood to exit the cranial cavity. It follows a path that eventually leads to the internal jugular vein, effectively channeling blood away from the brain.

The inferior petrosal sinus, located at the base of the skull, drains the cavernous sinus and directly connects to the internal jugular vein. This sinus plays an important role in draining venous blood from the regions of the brain supplied by the dural venous sinuses, further facilitating the return of deoxygenated blood to the systemic circulation.

In contrast, the other choices do not accurately represent the drainage pathways into the internal jugular vein. The superior sagittal sinus and transverse sinus drain into the straight sinus and not directly into the IJV. Meanwhile, the inferior sagittal sinus merges with the straight sinus before draining into the confluence of sinuses but does not lead directly to the IJV. Hence, the identification of both the sigmoid sinus and inferior
