Ethmoid Bone

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.

No, Falx cerebri attaches to the Crista Gali of the ethmoid in the front of the skull.
The ethmoid bone forms the roof of the nasal cavity. Its perpendicular plate forms part of the nasal septum. Its curved projections form the superior and middle nasal conchae. Its superior projection is called the crista galli.

Projecting superiorly between the cribriform plates is a triangular process called the crista galli "rooster's comb." The outermost covering of the brain (the dura matter) attaches to the crista galli and helps secure the brain in the cranial cavity.
