FIG. 24. An important consideration in judging horses. Sagittal section 

 of digit and diptal part of metacarpus of horse: A, metacarpal bone; B, 

 first phalanx; C, second phalanx; D, third phalanx; E, distal sesamoid bone; 

 1, volar pouch of capsule of fetlock joint; 2, intersesamoidean ligament; 3, 4, 

 proximal end of digital synovial sheath; 5, ring formed by superficial flexor 

 tendon; 6, fibrous tissue underlying ergot; 7, ergot; 8, 9, 9', branches of 

 digital vessels; 10, distal ligament of distal sesamoid bone; 11, suspensory 

 ligament of distal sesamoid bone; 12, 12', proximal and distal ends of bursa 

 podotrochlearis. By an oversight the superficial flexor tendon (behind 4) 

 is not marked. (Courtesy of L. W. Sisson, from Anatomy of Domestic
