Mucous Membrane of the Cervix.—The mucous membrane of thecervix is much thicker and more transparent than that of the bodyof the uterus, from which it also differs in certain structural peculiari-ties. The general arrangements of its folds and surface have alreadybeen described. The lower half of the membrane lining the cavity ofthe cervix, and the whole of that covering its external or vaginal por-tion, are closely set with a large number of minute filiform, or clavatepapillae (Fig. 24). Their structure is similar to that of the mucous Fig. 24.
