The digital arteries and veins course almost immediately be- 

 neath the skin. Descending from above the fetlock joint they 

 follow the course of the flexor tendon and throw out innumerable 

 twigs and divergant ramifications to supply the surfaces, as well 

 as the deeper tissue substances of the foot. Those shown in this 

 plate are the perpendicular artery, circumflex coronary, artery 

 of the plantar cushion, preplantar ungual, venous network of the 

 larainal tissue, coronary plexus, and the deep cartilaginous layer 

 — all flanked by the plantar nerve, which interlaces them with 

 Humorous filaments.
