Anatomy of the Foot. 



The foot is not a mere block of horn, but is a composite 

 structure made up of particular parts, each with a certain work 

 to perform. There is an old saying, very full of truth, "No 

 foot, no horse." A knowledge of the structure of the foot is 

 very essential in learning to judge horses. 



Fig. 114. Exterior of the Hoof. 



Showing division into toe, laterals, and quarters. 



The exterior of the foot may be divided into five parts, 

 each including one-fifth of the circumference. These are the 

 toe, laterals, and quarters. 



From the interior outward, the parts of the foot are the 

 coffin bone, lower end of the small pastern bone, navicular bone, 

 extensor tendon, flexor tendon, lateral cartilages, plantar cush- 

 ion, pododerm or foot-skin, and the hoof. The foot also has its 

 blood vessels and nerves.
