Bone development on a humerus at birth, in children and adults. This illustration makes it possible to compare the development of the bone during these three ages. From birth to childhood, the bone structure is cartilaginous and flexible. We see it thanks to the aspect of the bone at the level of the epiphyses and the diaphysis. But we can also see it thanks to the area shown in pink. This area constitutes the epiphyseal plate. It is this epiphyseal plate that produces cartilage. This allows the bone to gradually grow and ossify. Bone growth ends between the ages of 18 and 25.
