The tentorium cerebelli is an integral part of the reciprocal tension membranes that divide some brain areas: the falx cerebri, the falx cerebelli, and the diaphragma sellae.

The tentorium cerebelli divides the brain into supratentorial and infratentorial structures. The importance of this weight-bearing role played by the human tentorium is widely recognized in the clinical literature (e.g. The thin nature of the tentorium cerebelli causes its contrast imaging to be low compared to surrounding tissues. With gadolinium-enhanced T1-weighted magnetic resonance imaging (MRI), the visibility of the tentorium is improved, however, a limiting factor is accessibility to the contrast [13]. The portion of the dura mater that is found here is called the tentorium cerebelli. Start studying Flax Cerebri and Tentorium cerebelli.
