The amountof the secretion is very scanty, and goblet-cells are not usually foundexcepting when the membrane is inflamed and just before and duringmenstruation, when the mucus is abundant. Mucus therefore formsan important constituent of the menstrual fluid. The stroma or interstitial tissue is composed of a network ofembryonic mesoblastic tissue, in which are cells of irregular shapesand sizes. Their nuclei are relatively large, almost filling the cell-body, and contain one or more well-marked nucleoli. The usualshape of a stroma-cell is bluntly elliptical, but it may be round or. Fig. 13. The Stroma of the Cor-poreal Endometrium. In the lowerpart of the figure the lymphoid ap-pearance of the stroma is well shown. THE UTERUS 19 C£Ry/CAL CAHAL fusiform. There is no definite arrangement of the cells beyond thefact that they often aggregate in whorls around the gland-tubulesand the blood-vessels. They appear to vary according to their posi-tion, being larger near the surface, where the network is more open,and smaller nearer the muscle. The network supporting the cellsis composed of collagen-fibrils andis best seen in sections stained byMallorys polychrome methylene blue(see PI. I). In addition to the aboveirregular stroma-cells, there areothers resembling round lymphocytes(see Fig. 13). To these the stromaowes its lymphoid appearance, andsome authorities regard them asyoung formative connective-tissuecells. Whatever their origin theyare present in great numbers, andfrom their resemblance to mono-nuclear and polynuclea
