This diagram shows the cut-away side view of the horse's foot below the knee. The bones from the knee to the toe include the cannon bone, the proximal sesamoid bone, the long pastern bone, the short pastern bone, the navicular bone, and the coffin bone. Running down the posterior of the foot are the super digital flexor tendon, the deep digital flexor tendon and the suspensory ligament. The coronet is directly above the hoof wall. The plantar cushion is above the frog within the hoof. The sensitive laminae form a layer of tissue that serves as a means of attachment for the hoof wall and the coffin bone. The white line separates the hoof wall from the sole.
