Uberon Homology note : 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];
