portion continues to the lower third of the radius; there it 

 becomes tendinous, and passing down over the knee continues 

 along the front of the leg and becomes attached to the upper and 

 front pirt of the os pedis. Action, to extend the leg. 



The flexor pedis perforatus originates from the inner and lower 

 part of the humerus; it passes down the back part of the leg, 

 becoming tendinous just above the carpus; below the pastern it 

 bifurcates, forming a ring for the passage of the tendon of the 

 perforans and becomes attached to the sides of the os coronoe. 

 Action, to flex the lower part of the leg. 



The flexor pedis perforans originates with the perforatus; its 

 fleshy portion passes down and is attached to the back part of 

 the radius; its tendinous portion, beginning at the knee, passes 

 down the leg between the cannon bone and the tendon of the 

 perforatus, over the back of the fetlock and through the arch 

 formed by the division of the tendon of the perforatus, and is 

 attached to the under surface of the os pedis. Action, to flex 

 the leg. 



The extensor pedis of the hind leg originates at the lower and 

 front part of the femur; its fleshy portion extends downward 

 along the front surface of the tibia to the hock, where it becomes 

 tendinous; passing thence down the front of the leg it is attached 

 in the same manner as the extensor pedis of the front leg. 

 Action, to extend the leg. 



The flexor metatarsi is divided into two portions — a muscular 

 and a tendinous. The tendinous part is a strong pearly white 

 cord, situated between the muscular portion and the extensor 

 pedis. It commences at the inferior extremity of the femur; 

 finally terminating in two branches — a large one inserted in front 

 of the superior extremity of the cannon bone and the other and 

 narrower one deviating outward to reach the anterior surface of 

 the cuboid bone. The fleshy portion originates on the anterior 

 face of the tibia and is inserted by two' tendons, one in the head 

 of the large metatarsal bone, the other in the small cuneiform on 

 the inner side of the hock. Action, to flex the hock. 



The flexor pedis perforatus of the hind leg originates at the 

 posterior lower part of the femur. Its fleshy portion extends 

 about halfway dowa the tibia, then, becoming tendinous, it 

 passes over the point of the hock, being continued down the back
