The carpal bones are held together by 

 dorsal and 'palmar ligaments. The pisi- 

 form hone has a distinct capsular liga- 

 ment. The arrangement of the syno- 

 vial membrane is represented by fig. 43. 

 The bases of the metacarpal holies are secured to the second row 

 of the carpal bones by fibrous bands called dorsal and palmar liga- 

 ments. That of the thumb has a true capsular ligame^it. 



FINGER JOINTS. 



The joint between the metacarpal bones and the first row of pha- 

 langes, is a ball-and-socket joint. It is secured by an internal and 

 external lateral ligament^^ (Fig. 40), which are very thick in pro- 

 portion to the size of the bone ; anterior or palmar ligament^'^^ 

 the extensor tendon taking the place of a posterior ligament. The 

 heads of the metacarpal bones are also connected by transverse liga- 

 ments.^* 



The second and third joints of the finger^^ are arranged upon the 

 same principle as the first, with the exception of the transverse liga- 

 ment.
