118 LABORATORY METHODS OP 



A band of fibrous tissue from the stroma encloses this 

 cell. This band is called theca follicnli, and is divided 

 in two parts, an inner and an outer. The first cell is 

 called primordial ovum. Just inside of the theca fol- 

 liculi is seen a granular zone, called membrana granu- 

 losa. Inside of this stratum is the discus proligerus. 

 Now, inside of all this is the ovum, a large circular 

 body, enclosed in two cell walls ; viz : the zona pellucida, 

 and the vitclline membrane. In this space between the 

 ovum and the vitelline membrane is found the vitellus. 

 Situated to one side of the litellus is located the ger- 

 minal vesicle. In the center of the germinal vesical 

 is the germinal spot. A Graafian follicle that has lost 

 its ovum is called a corpus luteum. The blood vessels 

 enter the ovary at the attachment of the broad liga- 

 ments and pass into the theca folliculi. The lymphat- 

 ics are most numerous . in the medulla. The nerves 

 are of both varieties, and supply the follicles. 

 THE: FAi,u)piAN TUBES. 



The fallopian tubes, as all other tubes, consist of 

 three coats. The mucous coat in these tubes is lined 

 with ciliated epithelial cells. The blood vessels are 

 the same as in the other cases. 



THE UTERUS. 



The uterus is the same in structure, only the muscu- 

 lar tissue predominates in this organ. The Nabothian
