Synovial Joint Movements
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
Gliding Movement
Figure 8.5a
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
Angular Movement

Angular Movement
Figure 8.5c, d
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
Angular Movement
Figure 8.5e, f
Rotation
• The turning of a bone around its own long axis
• Examples– Between first two
vertebrae– Hip and shoulder
joints
Figure 8.5g
Special Movements
• Supination and pronation• Inversion and eversion• Protraction and retraction– Anterior to Posterior movement
• Elevation and depression– Superior to Inferior movement
• Opposition
