=====Falx cerebri=====
{{ http://upload.wikimedia.org/wikipedia/commons/f/ff/Falxcerebri.jpg?400}}
The [[falx]] cerebri, also known as the cerebral falx, its a dural brain covering, so named from its sickle-like form, is a strong, arched fold of dura mater that descends vertically in the [[longitudinal fissure]] between the [[cerebral hemisphere]]s.

It is narrow in front, where it is attached to the [[crista galli]] of the [[ethmoid bone]]; and broad behind, where it is connected with the upper surface of the [[tentorium cerebelli]].

Its upper margin is convex, and attached to the inner surface of the skull in the middle line, as far back as the internal occipital protuberance; it contains the superior sagittal sinus. Its lower margin is free and concave, and contains the inferior sagittal sinus.

The falx cerebri is known to calcify with age.

The falx is a more reliable guide than the [[anterior cerebral artery]] ACA in completing the posterior part of the intraventricular callosotomy
