THE FRONT LEG. 



Beginning at the top, the bones of the front leg are named 

 follows: shoulder-blade (scapula), arm-bone (humerus), 



forearm-bone* (radius), the 

 bones of the knee, cannon- 

 bone (Figure 55), the splint- 

 bones, of which there are 

 two, one each side of the 

 cannon-bone (A, Figure 59), 

 the sesamoids, upper and 

 lower pastern-bones, navic- 

 ular-bone, and coffin-bone 

 (Figure 56). 



The joints are the shoul- 

 der-joint, the elbow-joint, 

 the knee, the fetlock-joint, 

 the lower pastern-joint, and 

 the navicular-joint. 



The external nomencla-

 in Figure 57. 



The shoulder-blade, which 

 has no bony connection — no 

 articulation — with the trunk, is bound to it by muscles alone. 

 The horse has no collar-bone. Below, it articulates with the
