License Image This side view of an infants head shows the brain, the cut edge of the skull, the dura mater (green), arachnoid mater (blue) and sub arachnoid space.
License Image The brain is surrounded by three thin fibrous membranes. The dura mater is the outermost membrane (green) and is closely adherent to the inner surface of the skull. It is tough and inelastic. Below that is the arachnoid mater (blue), a thinner and more delicate layer. The pia is the innermost, very thin […]

When very young, a child or infants head is relatively large and the neck muscles undeveloped, providing very little support. During shaking, rapid acceleration-deceleration […]

This pooling of blood around the brain takes up space and causes increased pressure within the skull. After a period of time the blood in […]
License Image This side to side comparison of a normal infant brain and an injured infant brain, shows some important differences. In the injured brain image below: The subarachnoid space has all but disappeared as the injured brain swells and fills up the small space inside the skull. The ventricles have become compressed and flattened. […]
