Upper part of the ethmoid bone of the skull From Wikipedia, the free encyclopedia
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]
