JOINTS : A joint is an area were 2 bones meet. There are three types of joints: the ball and socket joint, (shoulders and hips), immovable joints, (in the skull), and freely movable joints, (arms,elbow, knee, etc.)

LIGAMENTS : There is also a Ligament, a ligament is tissue that connects bones to other bones. media type="youtube" key="27YWYflP_zg" height="236" width="455"

CARTILAGE: Cartilage is tissue that cushions between the bones (ex of cartilage is the nose ears)

FUN FACTS ABOUT THE SKELETAL SYSTEM: In the human skeleton, there are 206 bones all togther. The longest bone in the body is the femur. The smallest bone is the stapes, it helps you hear!
