[Biology_Online][VHOG] 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] UBERON:0008895 VHOG:0000315 VSAO labels this term 'pharyngeal arch' (2012-06-01) - however, it clearly means pharyngeal arch skeleton.
