GLANDS. 



The uterus, into which the ovum passes from the 

 Fallopian tube, possesses the same tissues in its walls, 

 only the second, or muscular coat, is much more 

 developed than in the oviduct, especially during ges- 

 tation. Its third, or mucous lining, is also more com- 

 plicated in its structure ; the portion of it which 

 belongs to the body of the organ resembles that of 

 the Fallopian tube, but that which lines its neck is 

 studded with filiform papillae which overlap each 

 other ; they are found near its inferior orifice ; in 

 addition, we have, in the mucous lining of the uterus, 

 large numbers of tubular glands, which have already 

 been described. 



The vagina has also three coats : the outer, fibrous ; 

 the middle, musculo-vascular ; and internal, mucous. 

 On the latter we find numerous deep rugae, especially 

 towards its orifice, and a large number of conical 

 papillae. Its epithelium is thick and stratified. Thus 

 far no glands have been found in the thickness of its 

 walls. 



and The arteries of the ovary enter that organ at its 

 lower border, and break up into a great many very 

 tortuous branches, of which some are distributed to 

 its parenchyma and fibrous envelope, whilst the rest 

 go to form a close capillary plexus in the walls of the 

 ovisacs. Its veins follow the track of the arteries, 

 and terminate in the ovarian and uterine veins. Its 

 lymphatics, whose origin is not fairly made out, 

 accompany the blood-vessels, and finally communicate 

 with the pelvic and lumbar glands. As to its nerves, 

 they run with its arteries into the secreting portion 

 of the organ, but their distribution and mode of ter- 

 mination are unknown.
