JOINTS OF HAND 



The other carpo-metacarpal joints are formed between the 

 bases of the four inner metacarpals and the trapezoid, os magnum, 

 and unciform. They are freely moving gliding joints. 



Ligament. A common capsule surrounds all four joints, which 

 includes also the intermetacarpal joints. There are numerous 

 interosseous ligaments binding* them all together. 



A synovial membrane lines all the joint cavities, which com- 

 municate with one another. 



Metaearpo-Phalang-eal Joints are between the heads of the 

 inetacarpal bones and the bases of the first phalanges.
