Fitted with a snaffle, the area of a horse's mouth, the lower jaw, where the mouthpiece lays, consists of two long bones with some skin over them and the tongue. This is not the area of contraction that makes us say the horse has a bad or a hard mouth. But it is the area, that causes the horse to react out of fear or sensitivity causing the muscles of the masseteric area, the muscles that attach the head to the neck, the hyoid apparatus, the TMJ and so on to yield or resist. When we are talking about loosening/relaxing a horses lower jaw we are talking about musculature and, like the rest of the skeletal frame, we have to loosen that musculature to direct it. There can be a lot of emotion in those muscles.
