Child's bone tissue, growth, bone development, cartilage structure, pediatrics. This drawing represents a child's humerus. In children the epiphyses (bone ends) are already made up of spongy bones, They are covered with articular cartilage as in adults. But they are still separated from the diaphysis (central part of the bone) by an area of epiphyseal cartilage. This area is shown in pink. This allows the child's bone to continue to grow in order to reach maturity in adulthood. A cut section is indicated at the level of the shaft of the bone.
