Which two bones form the sides and top of the cranium?

• A. Frontal bones
• B. Parietal bones
• C. Temporal bones
• D. Occipital bones

Answer: (C)

The correct answer identifies the temporal bones as the structures that contribute to the sides and top of the cranium. The temporal bones are situated at the sides of the skull and play a crucial role in surrounding the region where the brain is housed. They are important for protecting the structures of the inner ear and contributing to the formation of the lateral skull. The frontal bones are located at the front of the skull and do not form the sides or the top. Parietal bones are situated on the sides of the skull and contribute to the top, but they do not encompass the entire area as the temporal bones do. The occipital bones are found at the back of the skull and primarily form the base, which does not encompass the sides or the top of the cranium effectively. Thus, the unique positioning and structural contributions of the temporal bones justify their role in forming the sides and top of the cranium.
