If a muscle attaches from a rib to a point that is superior to that rib attachment, it will elevate the rib at the sternocostal and costospinal joints. The muscle would be contracting and pulling the rib upwards towards its superior attachment point. This action is called rib elevation, which is an important movement during inhalation as it helps to expand the thoracic cavity and increase lung volume.
