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.
