Step 1: Begin by identifying the anatomical location described in the question. The back of the skull refers to the posterior aspect of the cranium.
Step 2: Review the anatomical terms provided in the options. Each term corresponds to a specific structure in the skull: Occipital condyle, Mastoid process, External occipital protuberance, and Zygomatic arch.
Step 3: Understand the function and location of each term:
- Occipital condyle: Articulates with the first cervical vertebra (atlas) and is located at the base of the skull.
- Mastoid process: A bony projection behind the ear, part of the temporal bone.
- External occipital protuberance: A bony prominence at the midline of the posterior skull, part of the occipital bone.
- Zygomatic arch: The cheekbone, formed by the zygomatic and temporal bones.
Step 4: Match the description 'bony prominence at the back of the skull' with the correct anatomical term. The external occipital protuberance fits this description as it is a distinct projection on the occipital bone at the posterior skull.
Step 5: Conclude that the correct answer is 'External occipital protuberance' based on its anatomical location and description.
