DUCTULI EFFEBENTES 



As the tubules of the rete testis leave the mediastinum they 

 are abruptly transformed into peculiar efferent ducts, which pass 

 into the globus major of the 

 epididymis and by means of 

 spiral windings form coni- 

 cal masses, coni vasculosi, 

 whose apex projects into 

 the globus major. The epi- 

 thelium of these tubules is 

 peculiar in that it contains 

 two varieties of cells, and 

 in that it is thrown into

nal folds or rugae. 



In the lining epithelium there are short columnar cells which 

 rest upon the basement membrane and carry upon their free ends
