Synovial Joint Movements

1. Synovial Joint Movements

2. Gliding Movements • Simplest joint movements • One flat bone surface glides or slips over another similar surface • Examples – intercarpal and intertarsal joints, and between the flat articular processes of the vertebrae

3. Gliding Movement Figure 8.5a

4. Angular Movement • Flexion — bending movement that decreases the angle of the joint • Extension — reverse of flexion; joint angle is increased • Dorsiflexion and plantar flexion — up and down movement of the foot

5. Angular Movement Figure 8.5b

6. Angular Movement Figure 8.5c, d

7. Angular Movement • Abduction — movement away from the midline • Adduction — movement toward the midline • Circumduction — movement describes a cone in space • Quickest way to exercise the most muscles

9. Rotation • The turning of a bone around its own long axis • Examples • Between first two vertebrae • Hip and shoulder joints Figure 8.5g

10. Special Movements • Supination and pronation • Inversion and eversion • Protraction and retraction • Anterior to Posterior movement • Elevation and depression • Superior to Inferior movement • Opposition
