cervical glands become blocked, 

 which condition results in 

 the production of retention 

 cysts that appear as minute 

 vesicles between the folds of 

 the plicae palmatae. These 

 bodies were formerly de- 

 scribed as the ovules of Na- 

 both (ovula Nabothi). The 

 transition of the cylindrical 

 epithelium of the cervical 

 canal into the squamous cells 

 covering the vaginal portion 

 of the uterus takes place ab- 

 ruptly at the inner border of 

 the external os. At the inner 

 os, where the cervical mu- 

 cosa passes into that lining 

 the body, the change is so 

 gradual and inconspicuous 

 that no sharp demarcation 

 exists. 



The muscular coat, or 

 myomctriutu, although com- 

 posed of bundles of involun- 

 tary muscle arranged with 

 little individual regularity, 

 may be resolved into a n >bust 

 inner layer, in which the 

 bundles possess a general 

 circular disposition, and a 

 thin, imperfect outer layer in 

 which their course is for the 

 most part longitudinal. The 

 longitudinal muscle bundles 

 of the lYrMr outer laver, whi.-h is pn-srnt only over the fundus and body, are con- 

 tinued U v-.nd the uterus onto the tubes and into the broad, round, ovarian and
