Document Summary
Physical development and biological aging (1) body growth and change: Cephalocaudal pattern: the sequence in which the fastest growth in the human body occurs at the top (with the head): top to bottom growth. Sensory and motor development proceeds (the infant sees objects before than can control their torso and can use their hands before they crawl). Proximodistal pattern: sequence that starts at the center of the body and moves toward the extremities. Increase rapidly during infancy and slow down during childhood. Infancy: average north american newborn: 20 in long and weighs 7 and a half pounds. In the first several days, newborns lose 5 7% of their body weight. Once they adjust to suckling, swallowing and digesting the grow rapidly (gaining 5 6 ounces per week during the first month) Childhood: as the preschool child grows older, the percentage of increase in height and weight decreases with each additional year. Middle and late childhood: involves slow, consistent growth.
