STRUCTURE OF THE UTERUS. 



563 



are improperly termed follicles, constitute an "open gland" (Smith)] 



and which secretes the clear 



^ i 



viscid mucus of the cervix 



uteri. Here also occur 

 closed vesicles J to even 2 

 lines in diameter (ovula 

 Nabothi), composed of col- 

 lagenous tissue and a lining 

 of short conoidal cells, and 

 filled with a whitish, pearly 

 coagulated matter, contain- 

 ing glomeruli, cytoid cor- 

 puscles, oil-drops, and some- 

 times, also, cholesterine. 

 They are generally sup- 

 posed to be merely closed 

 rnucous follicles; but since 

 they sometimes occur where 

 no follicles exist, they must, 

 in some cases at least, be a 

 pathological new formation, 

 as cysts very often are in 

 other localities. In the 

 lower third or less, of the 

 canal of the cervix uteri, 

 L e. below the rugae just de- 

 scribed, are verrucose or 

 filiform papillae T J<j to ^ 

 of an inch long, covered 

 with conoidal 1 epithelial 

 cells. ( W. Tyler Smith, Fig. 

 389, c). Papilla only J to 

 j- as large as these, also 

 abound on the os uteri itself. (Fig. 389, B.) 



The mucous membrane of the oviducts (Fallopian tubes) is thin, 

 whitish-red, soft, connected to the muscular coat by a small quan- 

 tity of areolar tissue; and presents no glands nor villi, though it 

 has a few longitudinal folds. From the uterus to the free border of 



One of the four longitudinal columns of ruga; from the 

 virgin cervix. Magnified 9 diameters. (W. T. (jmith.) 



Kolliker states that these cells are also ciliated.
