Summary Introduction
Introduction:
The hands consist of carpal and metacarpal bones, which consist of small intrinsic muscles. These muscles help in flexing, extending, abducting, and adducting the fingers and opposing and reposing the thumb. When the thumb is rotated, flexed, and made to touch any fingers, it is known as an opposition movement.
