What is a falx cerebri?
The falx cerebri is a sickle-shaped structure formed from the invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.
Where is the falx cerebri located and what is its role?
The falx cerebri is a strong crescent-shaped sheet that represents an invagination of the meningeal layer of the dura mater into the longitudinal fissure, found between the medial surfaces of the cerebral hemispheres.
What is falx cerebelli anatomy?
The falx cerebelli is a small sickle shaped fold of dura mater, projecting forwards into the posterior cerebellar notch as well as projecting into the vallecula of the cerebellum between the two cerebellar hemispheres.
What is the difference between falx cerebri and falx cerebelli?
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.

dura
Falx cerebri is a sickle-shaped vertical fold of dura that begins anteriorly at the crista galli and winds around the corpus callosum between the two cerebral hemispheres to reach the falcotentorial junction on the superior aspect of the tentorium cerebelli (Fig. 2.1A).

What does falx cerebelli mean?
[edit on Wikidata] The falx cerebelli is a small sickle shaped fold of dura mater, projecting forwards into the posterior cerebellar notch as well as projecting into the vallecula of the cerebellum between the two cerebellar hemispheres. The name comes from two Latin words: falx, meaning “curved blade or scythe”, and cerebellum, meaning “brain”.
What is the posterior falx?
The posterior falx is the rear portion of the falx cerebri, an important part of the brain’s anatomy.
What does falx mean in Latin?
Falx is a Latin word originally meaning sickle, but was later used to mean any of a number of tools that had a curved blade that was sharp on the inside edge such as a scythe.
