What are the 22 bones of the skull?

The skull (22 bones) is divisible into two parts: (1) the cranium, which lodges and protects the brain, consists of eight bones (Occipital, Two Parietals, Frontal, Two Temporals, Sphenoidal, Ethmoidal) and the skeleton of the face, of fourteen (Two Nasals, Two Maxillae, Two Lacrimals, Two Zygomatics, Two Palatines, Two …

Why is the skull not one bone?

When growing is complete, the bones of the skull fuse together along the suture lines. These unions contain small amounts of fibrous connective tissue similar to those of the joints of arms and legs. Although the skull may structurally appear to be one piece when fully developed, it is still composed of separate bones.
