Verified step by step guidance

Understand the context of the question: The ethmoid bone is a cranial bone located between the eyes and forms part of the nasal cavity and the orbit. It has unique features that distinguish it from other bones in the skull.

Review the anatomical features listed in the question: Mastoid process, Coronoid process, Crista galli, and Foramen magnum. Determine which of these features is associated with the ethmoid bone.

Learn the definitions of each feature: The mastoid process is part of the temporal bone, the coronoid process is part of the mandible, the crista galli is a vertical projection of the ethmoid bone, and the foramen magnum is part of the occipital bone.

Focus on the crista galli: The crista galli is a prominent ridge on the superior aspect of the ethmoid bone. It serves as an attachment point for the falx cerebri, a membrane that separates the two cerebral hemispheres.

Conclude that the crista galli is the correct answer because it is a defining feature of the ethmoid bone, while the other options are features of different bones in the skull.
