HISTOGENESIS ENDOCRINE THE DEPARTMENT OF THE PANCREAS OF THE MARAL IN AGE ASPECT.
The first congestions small differential endocrine cells come to light simultaneously with exocrine in prefoetus the period, a differentiation hormone productive cells and increase in quantity areas in 1 mml are noted in the end early foetus the period. Islets differ in very small sizes considerably conceding to the sizes of trailer departments gland. Becoming endocrine parts as the functional system capable to adequate reaction, finally comes to the end in postnatale the period. At newborns small maral larger are noted islets, their big quantity on 1 mm2, the specific area of their surface in 1 mm2. The Great bulk islets make B-cell; they are larger A-cells. With the years diameter islets, quantity gradually decreases B-cells, butthe centers of quantity increases for 1 mm2 and their specific area. At old animals островков, the specific area of their surface, quantity diameter considerably decreases for 1 mm2. Quantity A-and B-cells becomes almost equal.
