Radiocarpal joints: condyloid synovial joint (synovial (condyloid) joint between the distal end of the radius and the articular disc overlying the distal end of the ulna, and the scaphoid, lunate and triquetrum.
-anterior and posterior ligaments strengthen the joint capsule
Movements: flexion, extension, abduction, addiction and circumduction. Greater is ulnar deviation coz radial styloid process gets in Ma way.
-oval articulate surface of one bone fits into complementary con cavity in another.

Metacarpal joints: synovial- condyloid joint

Carpometacarpal joint: synovial plane joint

Intercarpal joints: synovial-plane joints
