Distribution of A, B, and mixed pancreatic islets in two bird species (Anas platyrhincus Gallus gallus, Linné, 1758)--a morphometric study.
The structural configuration of the duck and chicken pancreas was studied using a morphometric technique and 3 different sampling types. The distribution and percentage of the various types of pancreatic islets are reported. Contrary to reports by other investigators, a larger proportion of type A islets was observed in each of the pancreatic lobes, and the established conclusion that A cells are present only in the splenic portion of the organ was not confirmed.
