Begin by identifying the location of the crista galli within the human skull. It is a small, upward projection located 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 anatomical relationship of the crista galli with surrounding structures. It is part of the ethmoid bone, which is situated between the eyes and forms part of the nasal cavity and the orbits.
Differentiate the ethmoid bone from other cranial bones such as the frontal, sphenoid, and temporal bones. The ethmoid bone is unique in its location and structure, contributing to the nasal cavity and the medial wall of the orbit.
Conclude that the crista galli is a projection from the ethmoid bone, based on its anatomical position and function within the skull.
