Vault of the Skull Opened, Showing the Falx Cerebri and Tentorum
The falx cerebri is a strongly-arched section of dura mater which separates the two hemispheres of the brain. Combined with the tentorum ceribelli, it supports and separates the primary sections of the brain (cerebellum, right cerebrum, and left cerebrum). The large open section in the center of the meningeal conjugation is where the corpus callosum passes from one hemisphere of the brain to another.
