The skull is a unique skeletal structure in several ways: embryonic cellular origin (neural crest and mesoderm), form of ossification (intramembranous and ) and flexibility (fibrous sutures).The cranial vault (which encloses the brain) bones are formed by intramembranous ossification.While the bones that form the base of the skull are formed by endochondral ossification.
