vessels. The nerves form in the tube wall a rich plexus, 

 from which fine branches proceed to the mucosa to end in the 

 neighborhood of the epithelial cells. 



C. Uterus. 



In the wall of the uterus there are three main coats : the 

 mucosa (endometrium), the muscularis (myometrium), and the 

 serosa (perimetrium). 



The mucosa lining the whole uterine cavity is at the time 

 of puberty about 1 mm. thick. It is covered on its surface by 

 a single layer of cylindrical ciliated epithelial cells, whose cilia 

 move toward the vagina, The tunica propria possesses many 

 connective-tissue cells and leucocytes contained in a fairly 

 dense connective tissue. Here there are found numerous 

 simple or dichotomously brandling tubular glands, which take- 

 on usually a coiled or corkscrew form in the deeper parts. 

 They are lined with a single layer of ciliated cylindrical cells,
