The hand is a highly complex region of the body allowing both fast and extremely accurate movements such as those seen in a skilled musician, while also having the ability to become strong and rigid as seen in a power lifter.
There are 27 bones in the hand. The eight short bones of the wrist or carpus are split into two main rows. The proximal row closest to the bones of the forearm are the scaphoid, lunate, triquetral and pisiform and the distal row consists of the trapezium, trapezoid, capitate and hamate.
The metacarpal bones make up the palm section of the hand which in turn lead to the 14 phalanx bones of the fingers and thumb. The thumb has two bones, proximal and distal while the fingers each have a third, intermediate phalanx.
There are also a number of sesemoid bones in the hand which are calcified parts of the tendons designed to improve the function of the tendon.
