Histomorphologic and morphometric study of pancreas in mehraban male sheep

Histomorphologic and histomorphometric studies on the pancreas of Mehraban male sheep were done in four age groups: fetus, neonate, young adult and old age In this respect, we used special stainings, light microscope and ocular micrometer. The results showed that the smooth muscles were absent in capsule. The tubular portion of exocrine pancreas was more prominent. Neuroinsular complex and beta unicellular islets were observed. The islet diameters were found between 51.01 to 96.09 microns. The capsule had not role in the secretion of pancreatic juice, the islet diameters increased by age
