external definition

Anatomical cluster that is part of the cranium and consists of the jaws, hyoid, and branchial arches.[AAO]

Anatomical cluster that is part of the cranium and consists of the jaws, hyoid and branchial arches.[TAO]

The part of the skull derived from the embryonic pharyngeal arches. [Biology_Online][VHOG]

external ontology notes

VSAO labels this term 'pharyngeal arch' (2012-06-01) - however, it clearly means pharyngeal arch skeleton.

many sources define this as the part of the endoskeletal that is from pharyngeal arches - this would make it part-disjoint from dermatocranium. However, there are many bones in AOs that have part-paths to both

homology notes

The skull of ancestral tetrapods has the three basic components that we have been considering: (1) chondrocranium, (2) splanchnocranium, and (3) dermatocranium (reference 1); Each part of the skull arises from a separate phylogenetic source. The most ancient part is the splanchnocranium (visceral cranium), which first arose to support pharyngeal slits in protochordates (reference 2).[well established][VHOG]
