homology notes

These (the epibranchial placodes) are focal thickenings of the embryonic ectoderm that form immediately dorsal and caudal of the clefts between the pharyngeal arches in all vertebrates, and they produce the neuroblasts which migrate and condense to form the distal cranial ganglia: the geniculate, petrosal and nodose ganglia. (...) 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]
