Step 1I'll solve this problem step by step, focusing on the concept of cephalocaudal development.
Step 2: Understanding Cephalocaudal Development
Cephalocaudal development is a principle of growth and motor skill development that describes how human development proceeds from the head (cephalic) region downward to the feet (caudal) region. This means that infants typically gain control of head and upper body movements before gaining control of lower body and extremity movements.
Final Answer
Infant gains control over the arms before the hands. This answer best illustrates the cephalocaudal principle of development, showing progression from larger muscle groups to more refined motor skills in a top-down sequence.
