What is falx cerebelli?

The falx cerebelli is a small infolding of the dura in the sagittal plane over the floor of the posterior cranial fossa. It partially separates the two cerebellar hemispheres 1.

What is the purpose of the falx cerebelli?

The function of the falx cerebri may be to constrain the brain and limit displacement and rotation inside the cranium [43,44].

What is the falx?

The falx cerebri is a sail-like structure which is anchored posteriorly at the internal occipital protuberance, superiorly to the periosteal dura mater, and anteriorly to the crista galli which sits above the ethmoid bone.[2] The superior and inferior sagittal sinuses form from spaces between the meningeal dura mater …

What is the difference between the 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.

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 does falx mean in Latin?
