15% in infants

3% in adults

8

In infants, a large proportion of blood volume is in --

the head

9

Why can brain tumors be missed in infants?

intercranial pressure can be less likely to be seen due to anterior fontanel

10

Reasons infants and young children are more susceptable to head injury

- top heavy
- large head in proportion to body
- excessive spinal mobility and immature muscles
