cells, each with a bundle of cilia on their free surface. 

 These are very easily detached, and therefore difficult 

 to find in a hardened and preserved specimen. But 

 in the fresh and well-preserved human uterus (Fried- 

 lander), as well as in that of mammals, the cells are 

 distinctly ciliated. The whole canal of the cervix is 

 also lined with ciliated epithelium, but in children, 

 according to Lott, only beginning from the middle. 

 The surface of the portio vaginalis uteri is, like that 

 of the vagina, covered with stratified pavement epithe- 

 lium. 



356. The mucous membrane of the cervix is 

 different from that of the fundus. In the former it is 

 a fibrous tissue possessed of permanent folds the 

 palmse plicatse. Few thin bundles of non-striped mus- 

 cular tissue penetrate from the outer muscular coat 

 into the mucous membrane. Between the palmse 

 plicatse are the openings of minute gland-tubes, more 

 or less cylindrical in shape. They possess a mem- 

 brana propria and a distinct lumen lined with a single 

 layer of columnar epithelial cells, which, according 

 to some, are ciliated in the new-born child, but, ac- 

 cording to Friedlander, non-ciliated. Goblet-cells are 

 met with amongst the lining epithelium. Several 

 observers (Kolliker, Hennig, Tyler Smith, and others) 

 maintain the existence of minute, thin, and long 

 vascular papillae projecting above the general surface 

 of the mucous membrane in the lower part of the 

 cervix ; these apparent papillae are, however, only due 

 to sections through the folds of the mucous membrane. 

 The mucous membrane of the fundus is a spongy 

 plexus of fine bundles of fibrous tissue, covered or 

 lined respectively with numerous small endothelial 

 plates, each with an oval flattened nucleus. The 

 spaces of this spongy substance are lymph-spaces, and 

 contain the glands and the blood-vessels (Leopold).
