![thelium is replaced by rounded cells. The capillaries of the mucous membrane run down between the tubes, forming a lacework on their surfaces and round their orifices. No true papillae exist in the mem- brane lining the uterine cavity. The mucous membrane of the uterus is peculiar in being always in a state of change and alteration, being thrown oif at each menstrual period in the form of debris in conse- quence of fatty degeneration of its structures, and re-formed afresh by proliferation of the cells of the muscular and connective tissues, probably from below upward, the new membrane commencing at the internal os. Hence its appearance and structure vary considerably Fig. 26. Vertical Section through the Mucous Membrane of the Human Uterus. (After Turner.) e.

The general arrangcsments of its folds and surface have already been described. The lower half of the membrane lining the cavity of the cervix, and the whole of that covering its external or vaginal portion, are (;losely set with a large number of minute filiform or clavate papillae (Fig. 27). Their structure is similar to that of the mucous membrane itself, of which they seem to })e merely elevations.
