  2. Wrist - Wikipedia

    en.wikipedia.org/wiki/Wrist

    In human anatomy, the wrist is variously defined as (1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; [1] [2] (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus [2] and; (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of ...

  3. Carpal bones - Wikipedia

    en.wikipedia.org/wiki/Carpal_bones

    The terms "carpus" and "carpal" are derived from the Latin carpus and the Greek καρπός (karpós), meaning "wrist". In human anatomy, the main role of the carpal bones is to articulate with the radial and ulnar heads to form a highly mobile condyloid joint (i.e. wrist joint), [1] to provide attachments for thenar and hypothenar muscles ...

    Bones of the human hand Hand-bone animation (metacarpal movement is exaggerated, other than on the thumb) Image showing the carpal bones. The skeleton of the human hand consists of 27 bones: [10] the eight short carpal bones of the wrist are organized into a proximal row (scaphoid, lunate, triquetral and pisiform) which articulates with the ...

  5. Joints of hand - Wikipedia

    en.wikipedia.org/wiki/Joints_of_hand

    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 . The carpometacarpal joint connects the carpal bones to the metacarpus or metacarpal bones which are joined at the intermetacarpal articulations .

    The small movements of the eight carpal bones during composite movements at the wrist are complex to describe, but flexion mainly occurs in the midcarpal joint whilst extension mainly occurs in the radiocarpal joint; the latter joint also providing most of adduction and abduction at the wrist.

  7. Pisiform bone - Wikipedia

    en.wikipedia.org/wiki/Pisiform_bone

    The pisiform bone is most recognizable as an unassuming palmar projection forming the heel of human hand. [2]The pisiform bone, along with the hamulus of the hamate, defines the medial boundary of the carpal tunnel [2] because the pisiform body acts as one of the four attachments points of the flexor retinaculum. [3]

  8. 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.

  9. Capitate bone - Wikipedia

    en.wikipedia.org/wiki/Capitate_bone

    The capitate bone is a bone in the human wrist found in the center of the carpal bone region, located at the distal end of the radius and ulna bones. It articulates with the third metacarpal bone (the middle finger) and forms the third carpometacarpal joint. The capitate bone is the largest of the carpal bones in the human hand.
