    adhesion of the folds after their formation, that is after the nineteenth week of foetal life. When the vagina is distended with menstrual blood, the hymen bulges forwards.1 As the menstrual blood accumulates, the vagina distends so as to form a tense membranous-walled sac nearly filling the pelvis, and with a smaller firmer body (the undilated uterus) rising from its upper surface (v. fig. 276). If the tension be not relieved, the cervix next becomes dilated and may rupture. Finally the uterus itself becomes opened out, though this does not occur till late. W^^f.> tP Fig. 274. Atresia Vagina, seen from behind. Thickness of obstruction (through which a probe is passed) 3-4 mm. ; of vaginal wall below atresia 2-3 mm., above it (at x) 6 mm. Dilatation of the body of the uterus is small compared with the common cavity formed by cervix and upper portion of vagina. Left Fallopian tube markedly dilated, with no distinct flexion on it, and changed at its free end into a thin-walled blood sac which had burst. Right tube undilated. (Brtisky). During this period, accumulations of blood may take place in the Fallopian tubes in the form of diverticula, usually situated towards the fimbriated end (figs. 274 and 275). These may be produced by a reflux of the blood from the distended uterus into the tubes, or by hemorrhage from the mucous membrane of the tubes themselves. That the latter may occur exceptionally has been mentioned at page 86. The uterine end of the Fallopian tube is in some cases closed. 1 Blood extravasations occurred into the labia in Davy's case.
