what is the function of the falx cerebri and the tentorium cerebelli?
The dura mater is partitioned into several septa, which support the brain. One of these, the falx cerebri, is a sickle-shaped partition lying between the two hemispheres of the brain. Another, the tentorium cerebelli, provides a strong, membranous roof over the cerebellum. A third, the falx cerebelli, projects downward from the tentorium cerebelli between the two cerebellar hemispheres.
