One of the weakest points on the human skull is the 'temple' region. This is known anatomically as the pterion (see the image above) and is formed by the junction of the frontal, parietal and sphenoid bones.

We draw the conclusion that the human skull is markedly asymmetrical not only with regard to the dimensions of individual bones but in the topological sense as well.

Are all skulls uneven?

The cranial bones are- Two parietal bones, two temporal bones, one ethmoid bone, one frontal bone, one occipital bone, and one sphenoid bone.

Do skulls shrink with age?

Using 3-D scans, scientists analyzed the faces of healthy men and women of different ages. They found that as we age, bones in the skull shrink, sink and slide around.
