Cytological studies were carried out in serial sections of the human vestibular ganglion obtained at postmortem examination. They were fixed with 2% osmic acid (pH 7.4) and LEVI's solution and stained with AZAN.The human vestibular ganglion was found as nodules among the vestibular myelinated fibers. In the vestibular ganglion the ganglion cells were seen among the loose collagen fibers and nerve fibers, separated from one another.These ganglion cells were bipolar and spindle shaped, varied somewhat in size and were mostly surroqnded by their myelin sheaths.Myelin sheaths of myelinated nerve fibers in the ganglion were usually thicker than the perikaryal myelin sheaths.In the ganglion there a few unmyelinated cells, which may belong to the autonomic nervous system.We are convinced that the human vestibular ganglion cells consist mostly of bipolar myelinated cells as in other mammals, such as the rabbit, bat, etc..
