Falx

Falx is a term used in anatomy to describe a sickle-shaped structure. The term is derived from the Latin word for sickle. In the human body, there are two structures referred to as falx: the Falx cerebri and the Falx cerebelli.

Falx cerebri[edit | edit source]

The Falx cerebri is a large, crescent-shaped fold of meningeal layer of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres. It is named for its sickle-like form. It is attached at the front to the crista galli of the ethmoid bone, and at the back to the tentorium cerebelli.

Falx cerebelli[edit | edit source]

The Falx cerebelli is a small sickle shaped fold of dura mater, projecting forwards into the posterior cerebellar notch and the vallecula of the cerebellum between the two cerebellar hemispheres.

Clinical significance[edit | edit source]

The falx cerebri and falx cerebelli are important anatomical landmarks in neurosurgery. They are often involved in cases of intracranial pressure, brain herniation, and meningioma, a type of brain tumor that can occur along the falx cerebri.
