Which of the following is a part of a hackamore that fits over and around the nose?

The bosal is a crucial component of a hackamore, specifically designed to fit over and around the horse's nose. This piece functions by applying pressure to the nose, enabling the rider to communicate and direct the horse effectively without the need for a bit. Usually made from rawhide or leather, the bosal allows for subtle cues, which can be vital in training and riding situations.

In contrast, the cheek piece is part of the overall bridle setup that helps attach the reins to the headgear but does not encircle the nose. The crown piece is the part of the bridle that sits at the top of the horse's head, supporting the structure but not directly related to the nose area. Lastly, the throat latch serves as a fastener under the horse's throat, ensuring the bridle remains securely in place, but it, too, does not come into contact with the nose. Thus, the bosal is distinctly recognized for its function in a hackamore, particularly concerning its placement around the nose.
