The stylopharyngeus muscle, which lifts the larynx, is a function of the third branchial arch. The superior laryngeal nerve, the cricothyroid muscle, the thyroid and cuneiform cartilage, and other tissues are all influenced by the fourth branchial arch. The cricoid, arytenoid, and corniculate cartilages, the recurrent laryngeal nerve, and all of the intrinsic laryngeal muscles are all derived from the fifth and sixth branchial arches (except the cricothyroid).
