i6 NAMES OF EXTERNAL PARTS. 



designation to include all the structures of the part is 

 " shank," as suggested to me by Professor Cossar Ewart. 

 The line dividing the shank from the fetlock is one 

 drawn across the leg immediately above the prominence 

 caused by the fetlock joint. 



The back-tendons (back-sineivs, M) are the fibrous 

 cord which runs down the back of the leg between the 

 knee and the fetlock, and which consists of two tendons 

 that lie closely together. 



The suspensory ligament is a fibrous cord which lies 

 between the cannon-bone and the back-tendons, and which 

 can be seen in a well-formed and sound leg that is not 

 unduly covered with hair (Fig. 360). 



The cannon-hone (/) is the bone which lies between the 

 knee and the fetlock. It has two small bones (outside 

 and inside splint bone) at its back. 



Fetlock (8). — The fetlock joint is the joint which the 

 cannon-bone" makes with the pastern. The term fetlock 

 (i.^., foot-lock) signifies the tuft of hair that usually grows 

 behind this joint, and also the joint itself and the enlarge- 

 ment made by the bones which form it. 



Pastern (9). — This is the short column of two bones 

 which is placed between the fetlock and the hoof. 



The hollow of the pastern is the hollow at the back 

 and lower part of the pastern. 



The coronet is the comparatively soft lower portion of 

 the pastern which is immediately above the hoof. 



The Hoof (10) is the horny substance which invests 

 and protects the lower part of the limb. "The front part 

 of the hoof, near the ground surface, is called the toe ; the 

 side portions, the quarters ; and the rear parts, on the 

 ground surface, the heels. The outer portion of the hoof 

 is termed the wall, which is divided into a hard, fibrous
