Shoulder and hip. Greatest ROM Hinge – allows joint to bend and straighten. Elbow, knee, ankle and fingers. Promotes rotation Pivot – limited rotation or turning of the head Ellipsoidal – aka gliding joints…allow bones to slide over one another. Wrist bonesPowerPoint Presentation: Ligament – band of fibrous, slightly elastic CT that attaches bone to bone. Stabilize movements Tendon – attaches muscle to bone to produce movement Review: Inflammation of a tendon is called what?School House Rock Video: School House Rock Video http://www.youtube.com/v/TOl1jIlsmFcI hope you have a better understanding of the skeletal system.
