Which bone articulates with the occipital condyles?Group of answer choicescoccyxcostal facetaxisatlas

Break Down the Problem

1. Identify the bone that articulates with the occipital condyles.
2. Review the options provided: coccyx, costal facet, axis, atlas.

Relevant Concepts

• The occipital condyles are rounded protrusions on the base of the skull.
• They articulate with the first cervical vertebra.

Analysis and Detail

1. Coccyx: This is the small bone at the end of the vertebral column. It doesn’t articulate with the occipital condyles.

2. Costal Facet: This refers to the surfaces on the vertebrae that articulate with ribs. It does not articulate with the occipital condyles.

3. Axis: This is the second cervical vertebra (C2) and, while it plays a role in the cervical spine, it does not directly articulate with the occipital condyles.

4. Atlas: This is the first cervical vertebra (C1) and it articulates directly with the occipital condyles, allowing for the nodding motion of the head.

Verify and Summarize

Based on the analysis, the only option that directly articulates with the occipital condyles is the atlas (C1), as it supports the skull and allows for its movement.

Final Answer

The bone that articulates with the occipital condyles is the atlas.
