The lax fibrous capsule of the wrist joint is strengthened on the 

 dorsal side by the broad ]J'j<tinentu)n r7iombolde.um } (posterior ligament), 

 which runs from the radius to the semilunar and cuneiform bones. Bet- 

 ween the styloid process of the radius and the scaphoid bone the exter- 

 nal lateral ligament, Lie/amentum latcralc radtalc, is attached- between the 

 styloid process of the ulna and cuneiform bone the internal lateral liga- 

 ment. Liffcuncntum Ifdcndc ut/un'c sen Funiculus ligcLmentosus, The intercarpal 

 and carpo-metacarpal articulations are strengthened by short, tense liga-
