NEURO-MUSCULAK MECHANISM

THE FOOT 



The physiology of the foot in the horse in these neuro- 

 muscular actions is of great importance (fig. 47). 



The anatomical study of the structure has taught that the 

 weight of the body is transmitted through the coronal bone 

 (second phalanx) (P.) to the foot, and that the articular 

 surface of the coronal is larger than that of the pedal bone

(third phalanx) (Pe.), so that it rests at its posterior part upon 

 the navicular bone (N.) and perforans tendon (P.T.). Further, 

 at each side of the pedal bone posteriorly are the large lateral 

 cartilages with a dense fibrous and fatty mass of tissue between 

 them (C.). The periosteum of the pedal bone is covered by a
