Mesodermal muscles of the fourth arch include the inferior constrictors and the laryngeal musculature while connective tissue components consist of the thyroid cartilage, cuneiforms, and part of the epiglottis. Arterial derivatives include the left aortic arch and the right subclavian. Acknowledged anomalies of this arch include asymmetric or stenotic larynx, laryngoptosis, chondromalacia, and double arch aorta.

The arteries are correct:
This how i see it: Skeletal muscles of the soft palate except tensor veli palatini. Skeletal muscles of the pharynx except stylopharyngeus.
Cricothyroid muscle
Cricopharyngeus
