C
Crista galli
D

Verified step by step guidance

Step 1: Begin by identifying the anatomical location of the inferior view of the skull. This view refers to the underside of the skull, which includes structures that interact with the vertebral column and other features of the neck.
Step 2: Understand the role of the first cervical vertebra (atlas). The atlas is the topmost vertebra in the spine and is responsible for supporting the skull and allowing nodding movements of the head. It articulates with specific bony features of the skull.
Step 3: Review the function and location of the occipital condyles. These are paired, oval-shaped bony projections located on the inferior surface of the occipital bone. They serve as the articulation points with the superior articular facets of the atlas, forming the atlanto-occipital joint.
Step 4: Eliminate the incorrect options based on their anatomical locations and functions: The coronoid process is part of the mandible, the zygomatic arch is part of the cheekbone, and the crista galli is a feature of the ethmoid bone located inside the cranial cavity, not on the inferior view of the skull.
Step 5: Conclude that the occipital condyles are the correct bony features located on the inferior view of the skull that articulate with the atlas, enabling head movements such as nodding.
