Your hand begins where your wrist ends. It includes your palm, fingers and thumb. Advertisement How are the hand and wrist structured? The bones of the hand can be divided into three distinct groups: Carpals Metacarpals Phalanges Each group of hand bones is important in its own right, but the eight carpals are especially interesting because they are arranged in two distinct rows and are direct contributors to the formation of the wrist.

Ulna. The ulna is one of the two forearm bones and is on the small finger side of the forearm. Unlike the radius, this bone does not twist, so when the hand changes position, the ulna is always in the same position on the inside part of the forearm. Like the radius, the ulna has joints at the elbow and wrist. It is made up of the wrist joint, the carpal bones, the metacarpal bones, and the phalanges. The digits include a medial thumb (when viewed with the palm down), containing two phalanges, and four fingers, each containing three phalanges. power and precision grips Key Terms. metacarpal: Any of the bones of the palm.; carpal: Any of the eight bones of the wrist.; phalange: One of the bones of the digits.; Carpals of the left hand: There are eight carpal bones in each wrist: scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitate, and hamate..

The human hand has 27 bones: the carpals or wrist accounts for 8; the metacarpals or palm contains five; the remaining fourteen are digital bones; fingers and thumb. The palm has five bones known as metacarpal bones, one to each of the 5 digits. These metacarpals have a head, a shaft, and a base. There are 7 bones forming the fingers in each hand.
