(6) The cervical epithelium which usually extends from the external to the internal os. This is very high and cylindrical; its nuclei are usually situated on the basement membrane, and are triangular, oval or elongate. The form appears to depend upon the amount of secretion contained in the cell. The cell protoplasm is very pale and tends to imbibe the hematoxylin stain instead of eosin. The racemose glands of the cervix may be looked upon as branching reduplications of the surface epithelium; their cylindrical epithelium is identical and continuous with that covering the surface of the canal. The stroma around the cervical glands is usually rather dense, but offers nothing very distinctive. (e) The uterine mucosa commences at the internal os and lines the entire uterine cavity. It is usually 2-4 mm. thick, is smooth, and has a surface covering of one layer of cylindrical epithelium. The cells are barely two-thirds as long as those of the cervix, have oval nuclei, which are situated some distance from the base of the cell or lie near the middle, and contain a protoplasm which takes the eosin stain; attached to their surfaces are cilia. Thus the cervical epithelium difi'ers in almost every particular from that of the body. The uterine glands are tubular and may branch slightly near the muscle; they are lined by one layer of epithelium, continuous with and similar to that covering the surface. This epithelium usually contains several nuclear figures. The tissue between the gl...
