Our skeletal muscle attaches to our tendons and it's the tendons that consist of collagen fibers that actually attach to our bone. Now tendons should not be confused with ligaments. Ligaments are those fibers that connect bone to other bones, but tendons are those fibers that connect our skeletal muscle to bone. So tendons and muscles basically work together to move our bones and that ultimately controls the movement of our body. It allows us to move in a wide range of different ways. Now there are many examples of muscle bone systems in our body and the example we're going to look at is the movement of our arm.
