When a horse is standing, muscles on opposite sides of the joints delicately contract and relax so that it stays in balance. This obviously puts considerable strain and stress on the muscles. To combat this, the horse has increased the fibrous content of many muscles. These collagenous muscles have been named collectively as the '''stay apparatus'''. This is further divided into the '''suspensory apparatus''' and the '''check apparatus'''. | When a horse is standing, muscles on opposite sides of the joints delicately contract and relax so that it stays in balance.
