As a child,young Quinton often went bowling with his father.First he would use a "ramp" to just push the ball off of,using mostly the muscles in his shoulders.As he got stronger and more coordinated,he would hold a light ball and flick it with his wrist.Finally,he learned to control the grip of his fingers to make the ball spin left or right.What developmental principle describes this pattern of increasing coordination from the center to the outside of the body?
A) The inside-out rule
B) The core-periphery rule
C) The cephalocaudal rule
D) The proximodistal rule

The proximodistal rule refers to the pattern of development where control and coordination of the body's central core, or proximal parts, develops before the ability to control and coordinate the extremities, or distal parts. This is evident in Quinton's development where he first uses his shoulders (proximal) to push the ball with a ramp, then his wrist (more distal), and finally learns to control the grip of his fingers (most distal).
