  2. Intercarpal joints - Wikipedia

    en.wikipedia.org/wiki/Intercarpal_joints

    Joints of the hand, X-ray. The bones in each carpal row interlock with each other and each row can therefore be considered a single joint. In the proximal row a limited degree of mobility is possible, but the bones of the distal row are connected to each other and to the metacarpal bones by strong ligaments that make this row and the metacarpus a functional entity.

  3. Condyloid joint - Wikipedia

    en.wikipedia.org/wiki/Condyloid_joint

    A condyloid joint (also called condylar, ellipsoidal, or bicondylar [1]) is an ovoid articular surface, or condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion , extension , adduction , abduction , and circumduction .

  4. Carpal bones - Wikipedia

    en.wikipedia.org/wiki/Carpal_bones

    In tetrapods, the carpus is the sole cluster of bones in the wrist between the radius and ulna and the metacarpus. The bones of the carpus do not belong to individual fingers (or toes in quadrupeds), whereas those of the metacarpus do. The corresponding part of the foot is the tarsus. The carpal bones allow the wrist to move and rotate ...

  5. Metacarpophalangeal joint - Wikipedia

    en.wikipedia.org/wiki/Metacarpophalangeal_joint

    These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges. [1] Being condyloid, they allow the movements of flexion, extension, abduction, adduction and circumduction (see anatomical terms of motion) at the joint. [1]

  6. Midcarpal joint - Wikipedia

    en.wikipedia.org/wiki/Midcarpal_joint

    The wrist is perhaps the most complicated joint in the body. It permits movements in two planes - extension/flexion, ulnar deviation/radial deviation - and allows complex patterns of motion under significant strain. Optimal wrist function requires stability of the carpal components in all joint positions under static and dynamic conditions.

  7. Joints of hand - Wikipedia

    en.wikipedia.org/wiki/Joints_of_hand

    The joints in the hand are joints found at the distal end of the upper limb.. The joints are: In the wrist there is the radiocarpal joint between the radius and carpus.Between the carpal bones are the intercarpal articulations and the midcarpal joint.

  8. Saddle joint - Wikipedia

    en.wikipedia.org/wiki/Saddle_joint

    The movements of saddle joints are similar to those of the condyloid joint and include flexion, extension, adduction, abduction, and circumduction. [1] However, axial rotation is not allowed. Saddle joints are said to be biaxial , [ 5 ] allowing movement in the sagittal and frontal planes.

  9. Synovial joint - Wikipedia

    en.wikipedia.org/wiki/Synovial_joint

    A condyloid joint is a modified ball and socket joint that allows primary movement within two perpendicular axes, passive or secondary movement may occur on a third axes. Some classifications make a distinction between condyloid and ellipsoid joints; [5] [6] these joints allow flexion, extension, abduction, and adduction movements (circumduction).
