Hand by the ability to be brought opposite to the fingers, a muscle action known as opposition. The skeleton of the human hand consists of 27 bones: the eight short carpal bones of the wrist are organized into a proximal row (scaphoid, lunate, triquetral and pisiform) which articulates with the bones of the forearm, and a distal row (trapezium, trapezoid, capitate and hamate), which articulates with the bases of the five metacarpal bones of the hand. The heads of the metacarpals will each in turn articulate with the bases of the proximal phalanx of the fingers and thumb. These articulations with
Bones (instrument) cutting of a yardstick. They are played by holding them between one's fingers, convex surfaces facing one another, and moving one's wrist in such a way that they knock against each other. One method involves placing the bones to either side of the middle finger such that approximately two-thirds of their length extends along the palm while the remainder protrudes above the fingers on the backside of the hand. The hand is held in a loose fist with the bones and the curled fingers roughly parallel to the palm, with the bone closest to the ring finger gently held against
