Area where the epiphyseal line is located? What is important about this line?
What is the metaphysis. This is where growth of the bone takes place.

What kind of fracture is only found in children?
What is a green stick fracture?
200
Bone disorder in which there is demineralization of the bone, due to osteoclast activity is greater than osteoblast activity. Treatment is?
What is osteoporosis? Treatment is weight bearing exercises, strength training (isometrics), and good intake of calcium and vitamin D. Best source of calcium is usually dairy products (most easily absorbed source).
