gliding/ plane joints | the relatively flat articular surfaces slide across one another with slight movement. ligaments usually restrict such movements. EXAMPLES:between carpals,tarsals,clavicles,and sternum |
hinge | permit angular movement in a single plane like the opening and closing of a door. EXAMPLE: elbow, interphalangeal joints, ankles, and wrist. |
pivot | nonaxial but they permit only rotation EXAMPLE: radius into ulna |
condylar joint/ellipisoid joint | an oval articular face nestles within depression in the opposing surface. EXAMPLES: metacarpals and wrist joints |
saddle joints | fit together like a rider in a saddle. each articular face is concave along one axis and concave along one axis and convex along the other. EXAMPLE: thumbs |
ball and socket joints | round head on one end rests in a cup shaped depression in another. EXAMPLES: humerus, femurs |
