The Six Types of Synovial Joints
1. ____ joint (monoaxial) - movements limited to flexion & extension as in knees, elbows and interphalangeal joints. Posses one concave & one convex articular surface
2. ____ joint (monoaxial) - allows movement that islimited to rotation such as radial joints. Possess one conical surface & one depressed surface
3. ____ joint (biaxal) - resembles to saddles, possesses movements of flexion, extension, adduction, abduction, opposition and circumduction, but ROTATION is not permitted. Only one is Carpometacarpal joint of the thumb
4. ____ joint (biaxal)- essentially reduced ball & socket joint. Contain one oval convex surface & one concave surface, allowing flexion, extension, abduction, adduction but Rotation is not permitted.. Examples are joints between fingers.
5. __ __ __ joint (Triaxal) - permit all movements & offer the greatest range of motion. One articulate surface is rounded, fitting in cuplike cavity. Examples are hip & shoulders joints
6. ____ joint (Triaxal) - permit all movements but are limited to gliding. Both articular surfaces are nearly flat. Present in acromioclavicular & intertarsal joints.
