<span>"Crista galli, </span>a superior projection on the ethmoid bone, attaches to the dura mater and secures the brain within the skull."

Crista galli is a vertical projection of the ethmoid bond where the falx cerebri attaches. The falx cerebri is a part of the dura mater that makes the division between the right and left hemispheres holding it into place.

<u><em>Crista galli</em></u> a superior projection on the <u>ethmoid </u>bone attaches to the dura mater and secures the brain within the skull.

Further Explanation:

The skull is the bony structure which protects the brain from shock and the gap between the skull and the brain is filled with cerebrospinal fluid. The ethmoid bone is a sieve like structure and spongy in appearance which is one of the eight bones of the cranial group of bones. It forms the anterior part of the cranial floor which acts as the medial wall between the orbits. The structures formed by ethmoid bone include crista galli, olfactory foramen, cribriform plate, superior nasal concha and middle nasal concha.

<u><em>Crista galli</em></u> is a triangular process which is a point of attachment for the falx cerebri of the dura mater. The outermost layer of the meninges is the dura mater where falx cerebri is the largest folds out of four folds of the dura mater.
