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
Normal mode medium determines what would be the interference pattern, thus determines the "ƒ"("x", "y", "z") form of the standing wave. This space-dependence is called a normal mode. Usually, for problems with continuous dependence on ("x", "y", "z") there is no single or finite number of normal modes, but there are infinitely many normal modes. If the problem is bounded (i.e. it is defined on a finite section of space) there are countably many normal modes (usually numbered "n" = 1, 2, 3, ...). If the problem is not bounded, there is a continuous spectrum of normal modes. In any solid at
