Question

Bones are hard structures and cannot be bent. But, we can still bend our elbow, knee, etc., How is this possible?

Answer 1

• Bending of our body parts such as the elbow, knee is possible due to the presence of different types of joints between the bones.
• Elbow and knee are not made up of a single bone but two or more bones are joined to each other by a hinge joint.
• This joint along with the muscles help us to bend the elbow and knee.
