One of a series of paired bulges that develop along the lateral walls of the foregut. The pharyngeal arches have developmental contributions from endoderm, mesoderm, and neural crest cells and are separated by anterior lateral endoderm out-pockets known as pharyngeal pouches.

homology notes
  • 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.[well established][VHOG]

terminology notes
  • Numbered cranial to caudal. different in mammals. branchial arch = ZFA:0001613 pharyngeal arch 3-7. generally gill arch 1 = pharyngeal arch 3. terminology varies as to whether branchial arch follows gill or pharyngeal numbering
