Articulatio radiocarpalis

 * articulating surfaces: facies articularis carpalis radii, proximal row ossa carpi (os scaphoideum, os lunatum, os triquetrum), discus articularis
 * The radius articulates directly with the ossa carpi
 * between the ulna and the ossa carpi is the discus articularis
 * meniscoid process

Articulatio mediocarpalis

 * articulating surfaces: os scaphoid, os lunate, os triquetrum form a socket for os capitatum, os hamatum; os trapezium, os trapezoideum forms a socket for the distal part of the os scaphoid
 * the shape of a recumbent S

Articulatio ossis pisiformis

 * stiff joint
 * articulating surfaces: os pisiforme, os triquetrum
 * the tendon m. flexor carpi ulnaris emerges from the os pisiforme
 * the flexor carpi ulnaris tendon is divided into 2 ligaments
 * 1) lig. pisohamatum (to hamulus ossis hamati)
 * 2) lig. pisometacarpale (to the base of the 4th + 5th metacarpals)

Articulationes intercarpales

 * joints with little mobility between the carpal bones of one row
 * ligamenta intercarpalia interossea=== Articulationes carpometacarpales ===
 * articulating surfaces: distal row of carpal bones, base of metacarpal bones

Art. carpometacarpalis pollicis

 * saddle joint
 * articulating surfaces: basis ossis metacarpi I, os trapezium
 * movements: palmar flexion, dorsiflexion, abduction, adduction, rotation, opposition, reposition
