Architecture Morphology and Histological Investigations of Pancreas in Golden Eagles (Aquila Chrysaetos)

The present study on the pancreas of golden eagle (Aquila Chrysaetos) revealed that it had a short, semi-wide, pale pinkish to white pinkish in colour, positioned between the limbs of duodenum loops and composed of two main lobes, dorsal and ventral lobes, that appeared extend from the origin of duodenal loop to one third length of the duodenal loop and another small lobe originated from the end of dorsal lobe towards the spleen which has been called splenic lobe. The lobes of pancreas were very short and not full the space between the two limbs of duodenum. Thus, there was a gap between the duodenal limbs. Histologically the pancreas of the golden eagle was covered by very thin layer of connective tissue capsule which formed from reticular, elastic and few collagenous fibers. The parancyma was mainly composed of exocrine glands. These glandular tissues were formed by triangular cells appeared in a single layer or observed as pyramidal shape. The endocrine gland of the pancreas showed that the islets of Langerhans were not numerous and observed as oval or circular in its appearance. Has two type of cells, the first one is alpha cells. Its nucleus has pale euchromatin. The second type was beta cells. This beta cells had dark hetrochromatin and large central nucleus. These cells were located in the peripheral of island of langerhans.
