MUSCLES OF FOREARM 



Although this is not a ball-and-socket joint, a certain amount 

 of circumduction is possible, and the movement of opposition i.e. 

 bringing the thumb right across the hand is due to a combina-

Ligaments. A capsule surrounds the joint which has strength- 

 ening bands in it, forming four ligaments. 



The synovial membrane lines the joint, which is quite separate 

 and distinct.
