Which bone forms the sides and top of the cranium and exhibits a diversity of hair textures?

The bone that forms the sides and top of the cranium, while also exhibiting a diversity of hair textures, is the parietal bone. The parietal bones are a pair of bones located on the upper sides and roof of the skull, and they play a crucial role in protecting the brain and supporting various structures of the overall head.

In terms of hair textures, the parietal region is significant because it encompasses the area where different hair types can be commonly observed. Hair textures can vary greatly, reflecting genetic diversity, as well as environmental influences, which may be particularly relevant in the areas of the head that the parietal bones protect. This anatomical context helps in understanding how the structure of the skull can relate to the aesthetics of hair.

The other bones mentioned do have their own functions and locations but do not contribute to the same extent in terms of hair textures or the cranium’s upper sides and roof. For instance, the occipital bone is situated at the back of the skull, the frontal bone forms the forehead, and the temporal bones are located at the sides near the ears. Therefore, when focusing on the sides and top of the cranium, the parietal bone is the most relevant.
