(...) 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] EHDAA2:0004623 UMLS:C0017406 facial ganglion EHDAA:6644 resolve facial VII vs geniculate (see EHDAA2) gVII MA:0001076 EFO:0003669 The group of sensory neuron cell bodies associated with the facial nerve (seventh cranial nerve).
