HORSESHOEING. 



29 



faces of the sesamoids and the upper end of the first phalanx. 

 The following ligaments are about this joint : 



1. Two lateral ligor 



merits, an external and Fig. 11. 



an internal ( Fig. 11, a). 



2. Two lateral sesa- 

 moid ligaments (f). 



3. An intersesamoid 

 ligament (Fig. 12, &), a 

 thick, fibrous mass, 

 binding the sesamoid 

 bones almost immovably 

 together, extending 

 above them and present- 

 ing on its posterior face 

 a smooth groove, i n 

 which glide the flexor 

 tendons o f t h e phal- 

 anges (perforans and 

 perforatus). 



4. The suspensory 

 ligament of the fetlock 

 (Figs. 11, c, 12, c, and 

 13, c, pages 29 and 30). 

 This may also be called 

 the superior sesamoid 

 ligament. It is a long 



and very powerful brace, originating on the lower row of carpal 

 bones (bones of the hock in the hind leg) and on the upper end 

 of the cannon between the heads of the two splint-bones, and 

 dividing at the lower third of the cannon into two branches (<?), 

 which are attached one to each sesamoid bone. Below these 

 bones these two branches are prolonged obliquely downward and 

 foru-ard on opposite sides of the long pastern to pass into the 

 borders of the anterior extensor tendon of the toe at about the 

 uaiddle of the long pastern (Fig. 14, &', page 32).
