Human Head Bones
Human Head Bones
The head of a human contains of 22 bones, consisting the cranium and the facial bones. The cranium is formed by 8 bones: the frontal bone, two parietal bones, two temporal bones, the occipital bone in the back, the ethmoid bone behind the nose, and the sphenoid bone. The cranium protects the brain, which, for an average adult male weighs about 1400 gram, but the female average brain mass is slightly less than that of males. Interesting fact is that Einstein's brain was of average size.The face consists of 14 bones including the maxilla (upper jaw) and mandible (lower jaw). The skull has many little holes in its base which allow the cranial nerves to travel to their destinations. At birth, the human skull is made up of 404 separate bony elements. Many of these bony elements gradually fuse together into solid bone as growth occurs. The bones of the roof of the skull are initially separated by regions of dense connective tissue.
