(...) The one substantial difference between the vertebrate pharyngeal arches and those of the protochordates is the presence of the epibranchial placodes but the evolution of these structures was undoubtedly driven by the endoderm.[well established][VHOG] FMA:53471 glossopharyngeal ganglion petrosal ganglion glossopharyngeal IX ganglion AS ZFA:0001301 TAO:0001301 ganglion of glosspharyngeal nerve cranial ganglion epibranchial ganglion
