Which of the following is NOT a bone found in the cranium?

The correct answer is C, as the term "axial" does not refer to a specific bone in the cranium.

In anatomy, the axial skeleton includes the skull, vertebral column, and rib cage. The bones that are specifically part of the cranium are the frontal, occipital, and temporal bones. Each of these plays a crucial role in protecting the brain and forming the structure of the head. The frontal bone is located at the front of the skull; the occipital bone is found at the back; and the temporal bones are located on the sides of the skull.

Since "axial" is a classification of the skeletal structure rather than a specific bone itself, it is correctly identified as not being a bone found in the cranium. This understanding helps clarify the anatomical classification of bones and their functions within the skeletal system.
