GLANDS OF MUCOUS MEMBRANE OF UTERUS. 479

 Weber, ff only present one form in Man, whilst in many 

 animals there are two varieties, though this is still to some 

 extent a moot point. JJ 



They form csecal tubes of various lengths, usually simple, 

 but often giving off from their centre, or just below this point, 

 two, or rarely several, branched tubes, which are either co- 

 lumnar or somewhat inflated near their extremities, and open 

 into the cavity of the uterus, upon the surface of the mucous 

 membrane. Looking down upon the free extremity, the dia- 

 meter of the opening of which is somewhat larger than that of 

 the gland canal, the tubes often appear laterally compressed 

 or triangular. They are twisted in the most diverse direc- 

 tions, and even form corkscrew-like coils, so that the total 

 length of the gland tube often considerably exceeds the thick- 

 ness of the mucous membrane. Taken collectively, however, 

 they preserve a vertical position in regard to the membrane, 

 especially at the lower part of the uterine cavity, and near the 

 openings of the Fallopian tubes, whilst in the upper part of 

 the body, and in the fundus, they assume an oblique and often 

 nearly horizontal position.
