The parts of your skeletal system that connect and support your bones include: 1 Cartilage. This is smooth and flexible, covering your bones where they meet. It acts as a cover that allows your bones to move against one another without any damage. As you age, your cartilage wears down and movement may become painful. 2 Immovable joints. The place where two bones meet is called a joint, and there are three types. Immovable joints, like those found in your skull, don’t allow the individual bones to move independently of one another. 3 Partly movable joints. These joints allow a small range of movement — for example, the bones in your rib cage are partly movable. They expand as you take a deep breath, but don’t have the same range of motion as joints like your knees and wrists. 4 Movable joints. These joints allow much more movement. They include your shoulders, knees, and elbows, among others. 5 Ligaments. These strong bands of connective tissue hold your bones in place alongside one another. 6 Tendons. This type of connective tissue connects your muscles and bones together.
