Part of the skull consisting of two parietal bones, the occipital bone, two temporal bones, the sphenoid bone, and the ethmoid bone. These are the parts of the skull covering the brain, or the braincase.

Confusingly, “cranium” is also sometimes synonymously with “skull.” It is more useful and more accurate to say that the skull is made up of the cranium and the face. The orbit, for example, is part of the face. It abuts, but is not really part of the cranium.  The frontal bone, in contrast, is recognized as being part of both the cranium and the face.
