Verified step by step guidance1
Understand the definition of the cranium: The cranium is the part of the skull that encloses the brain. It is composed of several bones that are fused together.
Identify the bones that are part of the cranium: The main bones of the cranium include the frontal bone, occipital bone, parietal bones, temporal bones, sphenoid bone, and ethmoid bone.
Examine the list of bones provided in the problem: Frontal bone, Occipital bone, Parietal bone, and Mandible.
Determine which bone is not part of the cranium: Compare the list of cranium bones with the provided options. The mandible is not part of the cranium; it is the lower jawbone and is not involved in enclosing the brain.
Conclude that the mandible is the bone not considered part of the cranium, as it is not involved in forming the protective case around the brain.
