1.	Bones are hard structures and cannot be bent. But, we can still bend our elbow, knee, etc. How is this possible?
Answer» Elbow and knee are not made up of a single bone, but two or more bones which are joined to each other by a joint (Hinge joint). This joint along with the muscles help us to bend the elbow and knee.
