Verified step by step guidance

Step 1: Understand the anatomy of the atlas (C1 vertebra). The atlas is the first cervical vertebra and is responsible for supporting the skull and allowing nodding movements of the head. It articulates with specific regions of the skull.

Step 2: Identify the occipital bone as the part of the skull that interacts with the atlas. The occipital bone is located at the base of the skull and contains structures that facilitate articulation with the atlas.

Step 3: Focus on the occipital condyles, which are rounded projections on the occipital bone. These condyles are the specific regions that articulate with the superior articular facets of the atlas, forming the atlanto-occipital joint.

Step 4: Eliminate the incorrect options. The sphenoid bone is located in the middle of the skull and does not articulate with the atlas. The mandibular fossa is part of the temporal bone and is involved in the temporomandibular joint, not the atlanto-occipital joint. The temporal bone itself does not directly articulate with the atlas.

Step 5: Conclude that the occipital condyles are the correct answer, as they are the specific regions of the skull that articulate with the atlas (C1 vertebra). This articulation allows for the nodding motion of the head.
