Study Notes

Dura Mater Folds

The falx cerebri is a large vertical fold of dura mater that separates the two cerebral hemispheres.
The tentorium cerebelli is a horizontal fold of dura mater that separates the cerebrum from the cerebellum.
The dura mater, the outermost layer of the meninges, forms these two important folds.
Falx cerebri serves to prevent the two hemispheres from shifting and colliding with each other during movement.
Tentorium cerebelli protects the cerebellum from pressure from the cerebrum and also allows for the passage of blood vessels to the brain.
