How do bones break and heal?


Listen


Your bones are tough stuff - but even tough stuff can break. Like a wooden pencil, bones will bend under strain. But if the pressure is too much, or too sudden, bones can snap. You can break a bone by falling off a skateboard or crashing down from the monkey bars.
When a bone breaks it is called a fracture (say: frak-chur). There's more than one way to break or fracture a bone. A break can be anything from a hairline fracture (a thin break in the bone) to the bone that's snapped in two pieces like a broken tree branch.
