Synovial Joint's

1. Gliding plane Joints

   • No angular or rotational movement
   • bony surfaces slide over each other
   • Examples
     • Tarsus of the foot
     • Carpus of the Hand

2. Ball & Socket

   • always involves a long bone
   • 3 or more directions
   • examples
     • Hip joint
     • Shoulder joint

3. Saddle Joints

   • articulating surfaces of the bones are reciprocally saddle-shaped
   • Carpometacarpal
   • Example
     • Thumb

4. Hinge Joints

   • Allows angular movement
   • One plane only
   • Examples
     • Elbow joint
     • Knee

5. Pivot Joint

   • Examples
     • radial ulna joint
   • moves round a central axis,
   • Allows rotational movement

6. Condyloid (ellipsoid) Joint

   • ovoid head fits into an elliptical cavity
   • Allows movement in two different planes
   • Cannot be rotated
   • Examples
     • Knee Joint
     • Inter Phalangael
     • wrist joint
