Histological Study of Exocrine Pancreas in Kestrel (Falco tinnuclulus)

Abstract

The purpose of this investigation was to study the histologicalcal structure of exocrine pancreas on ten healthy adult male of kestrels (Falco tinnuclulus).
After anesthesia, tissues pieces were dissected from the lobes, samples were fixed in
formalin processed and stained by H&E ,PAS and Masson trichrome stains for light
microscopic study .The pancreas is located on the right side of the abdomen between
the ascending and descending loop of the duodenum ,it consists of dorsal, middle and
ventral lobe ,it was hard to recognize between the three lobes .Microscopic examination showed that the pancreas covered with a very thin layer of connective tissue
with flattened mesothelium cells .The exocrine unit (tubuloacinar glands) comprised
of pancreatic acini were pear, spherical to ovoid in shape and ducts .The acini unit
lined by single layer of pyramidal cells had dark circular nucleus in the central part
of the cell. The duct system were arranged as intercalated ducts, intra lobular ducts,
inter lobular ducts and main pancreatic ducts. In conclusion ,it has been discovered
with the exception of a few secondary characteristics, the exocrine histological structure of the Kestrel (Falco tinnuclulus) pancreas is identical to that of other bird species.
