<span>A partially movable joint is a joint
in which its movement is limited to a certain amount. They are usually supported
by a layer of cartilages and fibrous connective tissues. They are also called
amphiarthrosis joints. Example of this are the joints formed by adjacent
vertebrae containing intervertebral disc of a cartilage. When the joints are
moved, it limits its movement because of
this arrangement. Other examples of this are the ribs and the sternum. Notice that
you cannot twist your upper body at 360 degrees without moving your lower body.</span>
