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]
Structure
Attachments
The falx cerebri (a fold of the dura mater surrounding the brain ) attaches to the crista galli. [ citation needed ]
Relations
The olfactory bulbs of the olfactory nerve lie on either side of the crista galli on top of the cribriform plate. [ citation needed ]
Variation
The base of crista galli varies in height. [2]
