Anatomy of the Foot.—This illustration represents the foot of a horse sawed from above the fetlock down through the center of the foot. It shows the structure of the foot, the name of each part being given according to number. 1. Lower end of large metacarpal, or cannon bone. 2. Bursa, which secretes the joint oil that lubricates the place where the tendon, or cord, on the front of the leg passes down over the front of the fetlock joint. This is important as it sometimes gets injured and becomes enlarged. It is then called a bursal enlargement, and is of the same nature as a wind gall. 3. Fetlock joint. 4. Os suffraginis, or large pastern bone. 5. Pastern joint. This joint is important; when diseased it is the seat of a high ringbone. 6. Os coronae or small pastern bone. 7. Coffin joint. This joint is important, for when it is diseased it is known as a low ringbone. 8. Wall of the hoof. 9. Os pedis, or coffin bone. 10. Sensitive wall, or quick of the foot. 11. Sensitive sole, or quick of the foot. 12. Frog of the foot, or horney frog. 13. Plantar cushion, or fatty frog. 14. Navicular bone. This is also important, for when diseased it is the seat of navicular, or coffin joint lameness. 15. Back tendons below the fetlock. 16. Sesamoid, or fetlock bones. 17. Skin. 18. Back tendons above the fetlock. - Deep muscles of the horse
