Which term describes growth that progresses from the head downward?

• A. Cephalocaudal development.
• B. Proximodistal development.
• C. Distal-proximal development.
• D. Central-peripheral development.

Answer: (A)

Growth that progresses from the head downward is cephalocaudal development. This means that development begins with the head and neck and then moves toward the trunk and finally the legs. In practical terms, infants first gain head and neck control, then trunk stability, and only later develop full control of the arms and legs. This sequencing is seen in motor milestones, where head control appears before sitting upright and then before standing or walking. Understanding this pattern helps clinicians assess whether a child’s motor development is progressing in the expected order. Proximodistal development, by contrast, describes growth from the center of the body outward (from the torso to the limbs), which is the opposite directional pattern. The other terms aren’t standard ways to describe this head-to-toe progression.
