<P> The ball and socket joint (or spheroid joint) is a type of synovial joint in which the ball - shaped surface of one rounded bone fits into the cup - like depression of another bone . The distal bone is capable of motion around the sausage's indefinite number of axes, which have one common center . It enables the bone to move in many places (nearly all directions). </P> <P> An enarthrosis is a special kind of spheroidal joint in which the socket covers the sphere beyond its equator . </P> <P> Examples of this form of articulation are found in the hip, where the rounded head of the femur (ball) rests in the cup - like acetabulum (socket) of the pelvis, and in the glenohumeral joint of the shoulder, where the rounded head of the humerus (ball) rests in the cup - like glenoid fossa (socket) of the shoulder blade . The shoulder includes a sternoclavicular articulation joint . </P> <Ul> <Li> <P> Hip </P> </Li> <Li> <P> Shoulder </P> </Li> <Li> Details of hip joint . <Ol> <Li> Femur </Li> <Li> Femoral Neck </Li> <Li> Femoral Head </Li> <Li> Acetabulum </Li> <Li> Acetabular Labrum </Li> <Li> Pelvis </Li> </Ol> </Li> </Ul>
