490 UTERUS, BY DR. R. CHROBAK. 



tally, without in all instances following the course of the vessels 

 to the anterior and posterior surfaces of the organ. Upon the 

 whole, the cervix, in which nerve fibres may be followed as far 

 as to the mucous membrane, appears to contain more nerves 

 than the body (Kilian) ; * on the other hand, the fundus uteri 

 appears to be more sensitive than any other part of the mucous 

 membrane (Lazarewitsch f and others). 



In the uterus, doubly contoured and pale nerve fibres are 

 found, as well as, according to the researches of Frankenhauser, J 

 Koch, Kehrer,|| Luschka,1T Polle,** and others (at least in 

 animals), ganglia in the submucosa, with each of which two or 

 three pale nerve fibres are in connection. 



Further classification of the nerves is riot at present possible, 

 since their mode of termination in the mucous membrane is 

 not known. Kilian, Polle, and others, certainly describe the 

 entrance of the nerve fibres into the papillae of the cervix, and 

 Hjalmar Lindgren even finds a fine plexus of pale fibres with 

 intercalated highly refractile and finely granular masses which, 

 breaking up in a brush-like manner, extend to the epithelium. 

 The nervous nature of these fibres is not, however, altogether 

 beyond question. 



The distribution of the nerves in the muscular tissue of the 

 uterus has frequently, of late years, been the subject of in- 

 vestigation. According to Frankenhauser, ff pale fibres pro- 

 ceeding from dark-edged fibres form plexuses around the mus- 

 cles before they, becoming converted into nucleus- and then into 

 node-bearing fibres terminate in the nuclei of the muscle cells. JJ
