Your horse's back is a complex structure, built of nerve and muscle, tendon and ligament, cartilage and bone. At the core of the system, encased safely in the protective fortress of the vertebrae, runs the spinal cord, the superhighway of the nervoussystem. Every step, every turn, every movement a horse makes, from his poll to his tail, originates in the nerves of the spine, and every muscular action from his feet to his ears interconnects in some way with the muscles and tendons of his back and neck.
