Final answer:
The crista galli provides attachment for the Falx cerebri, an infolding of the dura matter, supporting and protecting the brain's cerebral hemispheres.
Step-by-step explanation:
The crista galli provides attachment for the Falx cerebri, which is one of the two infoldings of the dura matter that separate the two cerebral hemispheres of the brain.
The crista galli is a small upward bony projection located at the midline in the floor of the anterior cranial fossa and formed by the ethmoid bone. Its primary function is to serve as an anchor point for the dura matter, which is the outermost layer covering the brain.
