Following the cessationof the menstrual flow of blood, the entire mucous membrane rapidlyshrinks. The glands cease to secrete mucus ; they collapse, losetheir corkscrew appearance, and become narrow and straight. The 92 GYNECOLOGY surface-epithelium is soon repaired, the stroma-cells shrink in size,and the tissue looks more fibrous. Figs. 67 and 68 show the stateof the epithelium in the early stages of involution. The regenera-tion of the epithelium is commencing ; the glands near the surfaceare straight and collapsed; the stroma is denser. Eig. 68 repre-sents the deeper strata of the same section as Fig. 67, showingthat the deep glands are still crenated although shrunken. Fig. 69. Fig. 65. Showing a Point of Rupture in the Surface-EpitheliumTHROUGH WHICH Blood IS ESCAPING. The Outlines of the engorged capillariesare well seen. The vessels are all intact showing that in this case the bloodescaped by diapedesis. The faintly stained pink areas deeper in the sectionshow exuded serum filling up connective-tissue spaces in the stroma. Notethe patches of decidua-like cells around the crenated glands, x 65. shows the appearances three days after menstruation, and Fig. 70shows that by the sixth day the continuity of the surface-epitheliumin this particular case was completely restored. (4) The Interval. This is the long phase which follows involutionand precedes the premenstrual stage. It is not a resting stage ; infact there is probably no period of complete rest in the menstrualcycle. During the interval the epithelium of the surface and of the PUBERTY, MENSTRUATION, AND THE MENOPAUSE 93 glands has to be restored. In the ep
