The deep opening that separates the two hemispheres is known as the longitudinal fissure. One of these, the falx cerebri, is a sickle-shaped partition lying between the two hemispheres of the brain. Also to Evolution plays a significant part, as The falx cerebri, so named from its sickle-like form, is a strong, arched process which descends vertically in the longitudinal fissure between the cerebral hemispheres.

The falx cerebri (aka falx, cerebral falx) is a an arched down fold of duramater that is found between the cerebral hemispheres in the interhemispheric fissure.

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]. They protrude into the dural venous sinuses of the brain, and allow cerebrospinal fluid (CSF) to exit the subarachnoid space and enter the [1] The falx cerebri, diaphragma

This posteriorly located lobe lies over the tentorium cerebelli, while its medial surface faces the falx cerebri.. On the medial surface of the occipital lobe, its border is well defined. Falx Cerebri and Tentorium Cerebelli. The falx cerebri (or falx) is a scythe-shaped band of dura matter that separates a part of the cerebral hemispheres. Its inferior boundary is defined by the inferior sagittal sinus and straight sinus.
