Why do children's bones bend before they break? The osteoid density of a child's bone is less than an adult's. Juvenile bone is more porous than adult bone because the Haversian canals occupy a much greater part of the bone (Figure 4). This is the principal reason a child's bone can bend more than an . The long bone in a child is divided into four regions: the diaphysis (shaft or primary ossification centre), metaphysis (where the bone flares), physis (or growth plate) and the epiphysis (secondary ossification centre). In the adult, only the metaphysis and diaphysis are present (Figure 1).
KIDS and adult bones are all the same. differences & similarities Similarities & differences between children & adults. Children-A Human new born baby has approximately bones in his or her body. -As Kids grow, special cells at the end of bones add new calcium to the network of bone. Mar 08, · When babies are born they have over bones in their body, but by the time they reach adult hood they have So what happened to the rest? The difference between the total number of adult and baby bones is a relatively simple explanation. As you may know, when a baby is born, and for some time afterwards they have a soft spot on their head.
In adults the bones have stopped growing and those areas in the bone where growth occurred (growth plates) have fused. If a fracture involves an adult growth plate, it does not cause any special. Compared to a fully developed skull where the facial portion is about half that of the cranium, in a newborn baby, the facial portion is about 1/8th that of the cranium. This makes the fetal cranium look large compared to the facial bone area. An adult skull is made of 8 cranial bones and 14 facial bones totaling 22 bones.
