Vestibular ganglion was investigated in human embryos during developmental stages l3-23 (34-56 postovulatory days). Branches of the vestibular ganglion forming ampullar nerves were observed in ernbryos at stage I5. During the last embryonic stages (stage 22 and 23) the utriculo-ampullar, posterior ampullar, and saccular nerves were clearly distinguished.
