The muscles of the hand can be broken down into three main regions: The extrinsic muscles are located in the anterior and posterior compartments of the forearm. 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.

A very slight change in the length of the biceps causes a much larger movement of the forearm and hand, but the force applied by the biceps must be higher than the load. 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. Movements of the hand are mostly started by muscles in the forearm. Most of its movements are controlled by muscles that aren't located in the hand at all, but in the forearm.
