Q

what is cephalocaudal pattern

A

a sequence in which the earliest growth always occurs at the top- the head-with physical growth in size weight, and differentiation of features gradually working their way down from top to bottom
shoulders, middle trunk and so on

Q

in what areas does the cephalocaudal pattern grow

A

e.g. head area, as the top parts of the head-the eyes and brain-grow faster than the lower parts, such as the jaw

Q

according to the proximodistal pattern what is an example of what the baby can move first
