In the [[occipital bone]], the lower division of the [[cruciate eminence]] is prominent, and is named the '''internal occipital crest'''; it bifurcates near the [[foramen magnum]] and gives attachment to the [[falx cerebelli]]; in the attached margin of this falx is the [[occipital sinus]], which is sometimes duplicated.
In the upper part of the internal occipital crest, a small depression is sometimes distinguishable; it is termed the [[vermian fossa]] since it is occupied by part of the [[vermis]] of the [[cerebellum]].
