The wrist and hand are the most distal parts of the upper limb. They consist of several groups of bones connected via numerous articulations that facilitate fine movements of the hand, such as writing or drawing. From proximal to distal, these bones are divided into three groups:
The following video tutorial will introduce you to the anatomy of the wrist and hand.
Take the following quiz to test and reinforce your knowledge about this topic.
Use the following link to take a quiz on the other structures of the hand. Or customize your quiz entirely, choosing the terms that you want to be tested on.
Download the following PDF worksheets and learn the carpal bones.
Examine each bone one by one through our atlas gallery. Note that we will first guide you through the landmarks seen from the palmar perspective, and then through those visible on the dorsal surface of the hand.
Carpal bones | 8 irregular bones that comprise the root of the hand. Proximal row: Scaphoid, lunate, triquetrum, pisiform Distal row: Trapezium, trapezoid, capitate, hamate Joints: Radiocarpal, intercarpal, midcarpal, carpometacarpal |
Metacarpal bones | 5 long bones that comprise the roots of digits. Parts: Metacarpal base, body, head Joints: Carpometacarpal, intermetacarpal, metacarpophalangeal |
Phalanges | 14 long bones that comprise the skeleton of the digits. 5 proximal phalanges; 4 middle phalanges (absent in thumb); 5 distal phalanges. Each phalanx consists of: base, body, head. Joints: Metacarpophalangeal, interphalangeal |
