In the upper half or two-thirds of the cervix THE FEMALE REPRODUCTIVE ORGANS. 2X% the epithelium is ciliated columnar, similar to that of the body of theorgan. In addition to the scattered tubular follicles, the representa-tives of the usual uterine glands, numerous short mucous crypts,with expanded blind extremities, lie embedded within the mucosa ;these pour out the thick glairy mucous secretion which is character-istic of the glands of the cervLx. Not infrequently retention of thesecretion takes place in some of these mucous follicles, the glandsthen undergoing transformation into greatly-distended cysts, theovula Nabothi; these appear as translucent yellowish vesicles em-bedded within the mucosa and readily seen by the unaided eye.

With the recurrenceof each menstrual period the uterine mucous membrane under-goes changes destined to prepare this surface as a favorable placefor the reception and retention of the ovum during gestation in theevent of impregnation.
