It is more or less swollen, injected and, as a rule, secernating. The normal cervix is a cone of 2-3 cm. length which pro- trudes into the oral part of the vagina. On its apex is the os uteri which is surrounded by even folds of the pink mucosa. (Fig. 1.) Under normal conditions the cervix is dry without any considerable secretion and the os uteri is. p-;g. 1—Normal Cervix and Orificium Extern. tightly closed. During estrum a hyperemy is present, and the mucosa is moderately, but distinctly, injected; the os uteri and the cervical canal is then so far open that a finger or a large catheter can easily penetrate; an abundant, thin, glassy and mucous exsudate is discharged. The cervical canal is 6-17 cm. long and has a mucosa without glands. Zschokke says is has a stratified squamous epithelium, Martin, that is has a simple columnar epithelium, sometimes with ciliar cells. The mucosa has vertical folds which form in three places heavy rings, partly through an enlargment of the folds, and partly through a thickening of.
