The falx cerebri is the largest fold of meningeal dura mater in the cranium. It runs from the crista galli of the ethmoid bone anteriorly, back to the straight sinus and tentorium cerebelli posteriorly. Its superior margin forms the superior sagittal sinus while its inferior margin lays just above the corpus callosum and contains the inferior sagittal sinus.
