The cribiform plate and crista galli are part of the Ethmoid Bone. The Cribiform Plate forms the superior surface of the Ethmoid Bone which helps form the roof of the nasal cavities and floor of the anterior cranial fossa. The Crista Galli projects superiorly from the Ethmoid Bone between the Cribiform Plates. The outermost covering of the brain is attached to the Crista Galli and keeps the brain in place.
The crista galli is found on the skull in the cribiform plate of the ethmoid bone.
