Document Summary

The top parts of the head (the eyes and brain) grow faster than the lower parts like the jaw. Shaken baby syndrome involves brain swelling and hemorrhaging. Physical developments tend to follow 2 patterns: cephalocaudal pattern. The sequence in which the greatest growth in size, weight, and feature differentiation gradually works down from top to bottom. This same pattern occurs in the head area: proximodistal pattern. The sequence in which growth starts at the centre of the body and moves toward the extremities. E. g. : the early maturation of muscular control of the trunk and arms, as compared with that of the hands and fingers. Extensive brain development continues after birth, through infancy and later. Because the brain is developing so rapidly in infancy, the head should be protected from falls or other injuries and the baby should never be shaken. A neuron is a nerve cell that handles information processing at the cellular levels.
