[Comparative anatomical characteristics of the histological structure of the arteries at the base of the brain in various mammalian orders and species].

In 30 mammalian species specific peculiarities of the arterial structure has been revealed and their dependence on the type of the brain blood supply has been demonstrated. The architectonics of the blood supply sources is correlated with the structure of the wall in the arteries, immediately participating in dumping the blood stream during its transport to the brain.
