Early Development of the Stato-acoustic and Facial Ganglia

Abstract

The early embryonic development of the stato-acoustic and geniculate ganglia was documented in CBA/CBA mice by light and transmission electron microscopy. The geniculate ganglion was identified at the 12–15 somite stage with its origin from the epibranchial placode as well as the neural crest. The VIII ganglion develops later at the 25–27 somite stage, having its origin both in the otic vesicle and in the neural crest cells.
