Verified step by step guidance

Identify the location of the crista galli within the skull. It is a bony projection found in the anterior cranial fossa.

Understand the function of the crista galli. It serves as an attachment point for the falx cerebri, a membrane that separates the two cerebral hemispheres.

Recognize the bone associated with the crista galli. The crista galli is part of the ethmoid bone, which is located between the eyes and forms part of the nasal cavity and the orbits.

Differentiate the ethmoid bone from other cranial bones. The ethmoid bone is distinct from the temporal, frontal, and sphenoid bones, which have different locations and functions in the skull.

Conclude that the crista galli is a projection from the ethmoid bone, based on its anatomical location and function.
