64 ANATOMY OF THE DOMESTIC FOWL 



which originates on the inner part of the elbow. It extends to the 

 upper rim of the base of the main digit. 



The ligamentum radiale carpi radialis externum originates on the 

 outside of the head of the middle digit and inserts to the superior 

 tuber culum carpi radialis of the radius. 



The ligamentum carpi radialis, internum, a short ligament, extends 

 from the inside of the head of the main digit to the inner rim of the 

 carpi radialis. 



The ligamentum carpi interosseum is located between the carpal 

 bones. 



The ligamentum ulnare metacarpi internum is spread out between 

 the processus styloideus of the ulna and the tuberositas muscularis 

 on the upper side of the middle finger base at a point where the 

 second and the third metacarpi separate. 



The ligamentum ulnare metacarpi externum extends from the 

 tubercle of the distal extremity of the ulna, on the dorsal side, 

 to the tubercle on the base of the metacarpus. 



Ligamentum radiale metacarpi extends from the head of the inner 

 digit to a point near the tuberculum muscularis of the radius. 



The ligamentum transversum ossis carpi radialis et metacarpi is 

 located between the inferior tuberculum ossis carpi radialis and the 

 first metacarpal bone. 



There is another ligament between the tuberculum superiorus 

 carpi radialis and the first metacarpal bone. 



The ligamentum ossis carpi radialis internum et metacarpi extends 

 from the inner surface of the carpus radialis to the tuberositas mus- 

 cularis of the radius. 



The ligamentum ossis carpi ulnaris externum et metacarpi extends 

 from the ulnar carpal bone to the tuberculum of the metacarpal bone. 



The ligamentum ossis carpi ulnaris internum et metacarpi extends 

 from the processus uncinatus of the ulnar carpal bone to the tuber- 

 ositas muscularis of the metacarpal bone. 



Ligaments of the Finger. — The ligamentum pollicare connects the 

 thumb with the first metacarpal bone. 



The ligamentum anterius ossis metacarpi et prima phalangis 

 digiti secundi extends from the tuberculum articulare metacarpi, of 

 the proximal end of the metacarpus, to the tuberculum articulare of 

 the first phalanx of the second or large finger. Similarly attached, 

 are also an internal and a posterior ligament, or ligamentum internum 

 and ligamentum posterius.
