Directions of Growth
Captions available
The idea
Growth follows set directions: cephalocaudal, from head to feet; proximodistal, from the centre outward; and mass-to-specific, from large movements to fine.
In practice
Arm control arriving before finger control, and the head large before the legs catch up.
Where people slip
These directions are exam vocabulary; each names where growth starts and where it spreads.
Your place on the trail
Every lesson rests on earlier ones and opens later ones. Tap any to jump.
