The crista galli (Latin: "crest of the rooster") is a wedge-shaped, vertical, midline upward continuation of the perpendicular plate of the ethmoid bone of the skull,[1] projecting above the cribriform plate[2] into the cranial cavity. It serves as an attachment for the membranes surrounding the brain.[1]

The falx cerebri (a fold of the dura mater surrounding the brain) attaches to the crista galli.[citation needed]
The olfactory bulbs of the olfactory nerve lie on either side of the crista galli on top of the cribriform plate.[citation needed]
The base of crista galli varies in height.[2] A bifid crista galli may suggest intracranial extension of a nasal dermoid cyst.[3]
