The superior sagittal sinus runs along the attached margin of which dural fold and terminates posteriorly at the confluence of sinuses (torcular Herophili)?
- A Tentorium cerebelli
- B Falx cerebri ✓
- C Falx cerebelli
- D Diaphragma sellae
Correct answer: B. Falx cerebri
Explanation
The superior sagittal sinus lies in the superior attached margin of the falx cerebri, running from the crista galli anteriorly to the internal occipital protuberance posteriorly where it typically drains into the right transverse sinus. Arachnoid granulations project into it for CSF absorption. The inferior sagittal sinus runs in the free margin of the falx cerebri. The tentorium cerebelli contains the transverse and straight sinuses in its margins.
