Bone functions related to bone structures

All bones in our body perform different structures and functions. Because of these different functions the bones have different structures. Bones are shaped the way they are because of the directions the bones move. In between each bone that coordinates with the other there are tissues, cartilage, ligaments, and much more. These parts provide cushion, blood and much more for the bones to work. For example, the cartilage and ligaments holds both the bones together so that when we move we would not fall apart. In other words,  we would not be able to stand straight if it wasn't for the ligaments and cartilage to hold us together.
