Final answer:

The first pharyngeal arch gives rise to the palatopharyngeal arch, a muscular fold that helps control movements of the palate and pharynx during swallowing.

Step-by-step explanation:

The first pharyngeal arch gives rise to several structures, including muscles of the jaw and throat. One important structure derived from the first pharyngeal arch is the palatopharyngeal arch. This muscular fold extends from the lateral side of the soft palate to the side of the pharynx, helping to control movements of the palate and pharynx during swallowing.
