Question 14

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

Answer 1

Elbows and knees are not made up of a single bone, but two or more bones. These bones are joined to each other by a joint known as the hinge joint. A joint is a point where two bones meet and aid in the movements. This joint along with the muscles help us to bend the elbow and knee.
