The cribriform plate is enclosed between the two medial orbital walls extending anteroposteriorly from the crista galli to the planum sphenoidale. The crista galli (Latin: "crest of the rooster") is the upper part of the perpendicular plate of the ethmoid bone, which rises above the cribriform plate.The falx cerebri (fold of the dura mater) attaches to the crista galli.
