Types of synovial joints

Types of synovial joints are :

1. Gliding (plane) joint

  • Articulating surfaces are flat
  • Glides back-and-forth and side-to-side
  • Rotation is prevented

 

2. Hinge joint

  • Convex surface of one bone fits into concave surface of another
  • Movement is flexion- extension
  • Monaxial – in one plane

 

3. Pivot joint

  •  A round or pointed surface of one bone fits into a ring formed by another bone and a ligament
  • Rotation
  • Monaxial
  • Medial rotation – anterior surface toward midline
  • Lateral rotation – anterior surface away from midline

 

4.Condyloid joint

  •  An oval-shaped condyle of one bone fits into an elliptical cavity of another bone.
  • Flexion-extension
  • Adduction-abduction
  • Biaxial
  • Adduction- movement toward midline
  • Abduction – movement away from midline

 

5. Saddle joint

  • One bone shaped like a saddle; the other like a rider sitting in the saddle
  • Flexion-extension
  • Abduction- adduction
  • circumduction
  • Biaxial
  • Allows opposition of thumb

 6. Ball and Socket joint

  • Ball shaped surface of one bone fits into a cuplike depression of another
  • Flexion-extension
  • Abduction-adduction
  • Circumduction
  • Rotation – movement around longitudinal axis
  • Triaxial
