Which muscle attaches to the buccal shelf?

  1. Genioglossus

  2. Buccinator

  3. Palatoglossus

  4. Superior constrictor

The correct answer is: Buccinator

The other options are incorrect because they are muscles that either attach to different parts of the mouth (genioglossus attaches to the tongue, palatoglossus attaches to the soft palate) or are located in different regions of the mouth (superior constrictor is located in the pharynx). The buccinator muscle is specifically responsible for compressing the cheeks against the teeth and plays an important role in mastication (chewing) and facial expressions.
