    my guess

    Arches IV & VI: (Arches merge during development) form neck structures: Form the laryngeal cartilages (thyroid, cricoid, etc.). These cartilages are all derived from lateral plate mesoderm.

    i don't know

    Does the larynx develop from the endodermal lining/adjacent mesenchyme of the foregut between the fourth and sixth branchial arches ? or does it develop from lateral plate mesoderm as mentioned above?
