Structure[]

The crista galli is the upper part of the perpendicular plate of the ethmoid bone of the skull.^[1] It rises above the cribriform plate.^[2] The falx cerebri (a fold of the dura mater surrounding the brain) attaches to the crista galli. The olfactory bulbs of the olfactory nerve lie on either side of the crista galli on top of the cribriform plate.

Variation[]

The crista galli varies in height.^[2] In most people, it extends slightly below the cribriform plate.^[2] In around 28%, it is completely above the cribriform plate, whilst in around 8%, it is over 50% below the top of the cribriform plate.^[2]
