COMPARATIVE MORPHOLOGY OF THE AMPULLA OF THE PHATERNAL PAPILLA IN MAMMALS WITH AND WITHOUT GALLBLADDER
Keywords:
To study comparative morphology of ampulla of the phaternal papilla in animals with and without gallbladder., ampulla of the phaternal papilla, comparative morphology.Abstract
Morphological features of the ampulla of the phaternal papilla of rats as representatives of animals without gallbladder and rabbits - animals with gallbladder were studied. The picture of internal relief of the ampulla mucosa was reconstructed by the method of obtaining serial histotopographic slices from the level of formation of the ampulla of the phaternal papilla up to its mouth with the following consecutive morphological and morphometric analysis. Paraffin sections of the material were stained with hematoxylin and eosin, Van Gieson, Mallory and Grimelius methods.
It was found that the relief of the mucous membrane of the ampulla of the phaternal papilla of rats and rabbits differs significantly. In rats the ampulla cavity is smooth and has small depressions. The mucous membrane of the ampulla of the faternal papilla of rabbits forms folds, which forming anastomoses among themselves form a trabecular network.
