LESSON XXXV. 



TISSUES OF REPRODUCTION. 



1. Ovary. Longitudinal section of ovary of a 

 mammal, e.g. cat, passing through the hilus (mercuric 

 chloride, stained in bulk, cut in paraffin). 



Observe first with a low and then with a high 

 power 



The germinal epithelium, consisting of a single 

 layer of short columnar cells covering the surface of the 

 ovary except at the hilus. 



The connective tissue radiating from the hilus 

 throughout the ovary to form the stroma; in this 

 many blood vessels are seen ; towards the periphery 

 the fibrous tissue largely disappears ; immediately 

 underneath the epithelium the stroma forms a denser 

 layer. 



Small Graafian follicles forming a zone a short 

 distance below the germinal epithelium. 



Deeper (older) Graafian follicles of various sizes 

 scattered throughout the rest of the stroma ; in each of 

 these there is a more or less considerable, clear space. 



One or more corpora lutea (unless the ovary has
