Последний слайд презентации: Movable joints: Literacy
1. Elbow has two joints. Name those joints and give their functions (bending and rotating). 2. Explain how it would affect om movement if we had hinge joint instead of pivot joint in the neck? 3. What problems may occur if joint capsule is damaged and synovial fluid runs out?
