Finally, in adults, the head represents approximately 12% of the body length. The cephalocaudal trend is also the trend of infants learning to use their upper limbs before their lower limbs. The proximodistal trend, on the other hand, is the prenatal growth from 5 months to birth when the fetus grows from the inside of the body outwards.
The proximodistal trend is the tendency for more general functions of limbs to develop before more specific or fine motor skills. It comes from the Latin words proxim- which means "close" [ 1 ] and "-dis-" meaning "away from", [ 2 ] because the trend essentially describes a path from the center outward.
Proximodistal is the axis of an appendage such as an arm or a leg, taken from its tip at the distal part to where it joins the body at the proximal part. [ 12 ] In chest radiography , an X-ray image may be taken from different views including the front to back view ( anteroposterior ), the back to the front view ( posteroanterior ), and the ...
There is a genetic cephalocaudal (head-to-foot) trend in both prenatal and postnatal development. [ 2 ] As a baby grows, they learn to sit up, stand, walk, and run; these capacities develop in a specific order with the growth of the nervous system, even though the rate of development may vary from child to child.
Like physical growth, motor development shows predictable patterns of cephalocaudal (head to foot) and proximodistal (torso to extremities) development, with movements at the head and in the more central areas coming under control before those of the lower part of the body or the hands and feet.

Biological rules and laws are often developed as succinct, broadly applicable ways to explain complex phenomena or salient observations about the ecology and biogeographical distributions of plant and animal species around the world, though they have been proposed for or extended to all types of organisms. Many of these regularities of ecology ...

The digits also have a quasi-periodic arrangement along the proximodistal axis, consisting of tandem chains of skeletal elements. The generation of the basic limb plan during development results from the patterning of the mesenchyme by an interplay of factors that promote precartilage condensation and factors that inhibit it.
