21. It allows the young child’s brain to rotate more readily in response to head acceleration or deceleration than occurs after the skull base has developed more prominent bony ridges and concavities The shallow skull base It produces instability of the head , which allows greater movement of the head and brain when acted on by acceleration–deceleration forces. The large heavy head mounted on the weak neck The large number of neurons without glial or dendritic connections, and the small axonal size predispose the young brain to shearing injury by creating a soft consistency. The paucity of the myelin sheath of axons Impact force is more effectively transferred through the thin pliant skull and across the large and shallow subarachnoid space of a young child’s head. Thinness and pliability of the skull with large heavy head Mechanism of injury Characteristic
