later ale externum. 



The three articulations which form the elbow-joint have a common 

 fibrous capsule, which is inserted superiorly a little above the trochlea and 

 radial head of .the humerus, and runs down to the margin of the greater 

 sigmoid cavity of the ulna ; it is not directly attached to the radius, 

 but to the a n n u 1 a r or orbicular 1 i g a m cut, Ltgamentum annuhtrc, 

 which surrounds the head of the radius, and is attached by each end 

 to the extremities of the lesser sigmoid cavity of the ulna. Of the two 

 lateral ligaments only the internal is attached directly to the ulna, 

 while the external is attached to the annular ligament.
