The second pharyngeal arch will form the hyoid apparatus. The cranial neural crest cells that populate the second pharyngeal arch emerge primarily from rhombomere 4 and will form skeletal elements.

A conserved feature of all vertebrate embryos is the presence of a series of bulges on the lateral surface of the head, the pharyngeal arches; it is within these structures that the nerves, muscles and skeletal components of the pharyngeal apparatus are laid down. The pharyngeal arches are separated by endodermal outpocketings, the pharyngeal pouches.[well established][VHOG]
