The palm has five bones known as metacarpal bones, one to each of the 5 digits. 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. Index finger, pointer finger, or forefinger.Each finger, starting with the one closest to the thumb, has a colloquial name to distinguish it from the others The four fingers on the hand are used for the outermost performance these four digits can be folded over the palm which allows the grasping of objects. The human hand consists of a broad palm (metacarpus) with 5 digits, attached to the forearm by a joint called the wrist (carpus). The scaphoid and the lunate are the two bones which actually articulate with the radius and ulna to form the wrist joint. The scaphoid bone crosses both rows as it is the largest carpal bone. Altogether there are 8 carpal bone which are arranged in two rows, proximal and distal
They form the wrist joint with the carpal bones. The Radius is positioned on the thumb side of the wrist, and the ulna on the little finger side. The Ulna is the larger of the two forearm bones, although it tapers at the wrist end, to become narrower than the Radius at this point. Repetitive use does however frequently lead to injuries.
It connects the forearm to the hand and allows a good range of motion. The wrist joint is the complex joint formed between the distal ends (furthest from the body) of the Radius and Ulna (two forearm bones) and the carpal bones.
