Bones, muscles and joints hold our body together and permit free movement of the body parts. They are a part of the musculoskeletal system. The bones provide stability to the body. Muscles are attached to the bones by tendons. They contract and expand to move the bones. Both muscles and bones are strong and connected to each other. In the absence of muscles and bones, it would be difficult to form the skeletal framework of the body. The functioning of bones and muscles is interdependent. Hence, both are stronger and are essentially required for body movement.
