The cellular elements of the neurohypophysis were investigated by Retzius (1894) who recognized their neuroepithelial nature. Bucy ('30, '32) separated these cells from other types of glia and called them pituicytes. Romeis ('40) distinguished several varieties of pituicytes and emphasized the technical difficulties encountered in the study of neurohypophyseal structures. However, the development of the silver-carbonate method of del Rio Hortega permits a much more detailed analysis than was possible with the older silver techniques and early variants of this observer. MATERIAL AND METHODS Human pituitary glands were used for this study. The ages of the patients ranged from 3 to 74 years. Because of the structural similarity between the neurohypophysis and the infundibulum the latter was also examined. The material was fixed in brom-formalin, cut vertically on a freezing microtome at 15 and impregnated with silver-carbonate. HISTOLOGIC EXAMINATION I n the infundibulum and the neurohypophysis there are 4 different types of pituicytes :
