ZFA:0001216 uberon VSAO:0000149 Subdivision of endoskeleton derived from pharyngeal arches 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] AAO:0010157 pharyngeal endoskeleton pharyngeal skeleton viscerocranium visceral cranium branchial arch skeleton XAO:0003176 gill arch skeleton Anatomical cluster that is part of the cranium and consists of the jaws, hyoid and branchial arches.[TAO] UBERON:0008895 TAO:0001216 pharyngeal arch skeleton visceral skeletal system Anatomical cluster that is part of the cranium and consists of the jaws, hyoid, and branchial arches.[AAO] visceral skeleton VHOG:0000315 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 The part of the skull derived from the embryonic pharyngeal arches.
