Are arranged in two rows of four (lateral to medial): Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, and Hamate (mnemonic device: Sandra Likes To Pat Tom's Two Cold Hands). (Trapezium precedes trapezoid alphabetically.)
Proximal row (lateral to medial): scaphoid, lunate, triquetrum, and pisiform
Except for the pisiform, articulates with the radius and the articular disk (the ulna has no contact with the carpal bones). The pisiform is said to be a sesamoid bone contained in the flexor carpi ulnaris tendon.
Distal row (lateral to medial): trapezium, trapezoid, capitate, and hamate
Metacarpals
Are miniature long bones consisting of bases (proximal ends), shafts (bodies), and heads (distal ends).
Heads form the knuckles of the fist.
Phalanges
Are miniature long bones consisting of bases, shafts, and heads. The heads of the proximal and middle phalanges form the knuckles.
