Normal Growth of the Sutures of the Skull

The processes of sutures and synchondroses formation, interdigitation and closure set the normal skull growth. Sutures and synchondroses represent growth sites in normal skull development. These articulations have distinctive characteristics due to their different embryological origins and histologies; sutural fusion occurs by either intramembranous ossification or chondroid bone formation whereas synchondrosis fusion occurs by endochondral ossification.
