Where two bones meet is called a joint. Joints allow for different degrees of movement, from (the sutures in the skull) to freely movable (the ball-and-socket joint of the shoulder or the hinge joint of the knee). Ligaments connect bone to bone, while tendons connect muscle to bone. Conclusion For an 8th-grade biology level, understanding the skeletal
