Which of the following is only found associated with a child's bone? Diaphysis Marrow cavity Epiphyseal plate Periosteum

The epiphyseal plate, also known as the growth plate, is primarily found in children's bones and is responsible for the growth in length of long bones. This area is composed of cartilage that gradually ossifies as a person matures, ceasing upon reaching the end of adolescence when bone growth concludes. The diaphysis is the shaft of the bone, while the marrow cavity is present in both children's and adult bones. The periosteum is a connective tissue that surrounds the bone and is also found in individuals of all ages. So, if you want to see the magic of growing bones, keep your eye on that epiphyseal plate!
