| Abstract | ||
| The present study was designed to find the macroscopic, microscopic and histocamical properties in pancreas of white-eared bulbul (Pycnonotus leucotis) and ductal system, ten healthy adult birds were transferred to the veterinary anatomy laboratory in Al-Qasim green university. Macroscopic study revealed that the pancreas was white in color, formed from two lobes, the ventral lobe navicular in shape while the dorsal lobe was very thin like triangular in appearance but longer than the ventral lobe. The two lobes were not occupy the space between the descending and ascending limbs of duodenum, the mean weight of birds and whole pancreas was (27.6±3.04), (0.07±0.022) gm respectively, the mean weight of dorsal and ventral lobes was (0.034±0.005), (0.036±0.0054) gm respectively and the mean length of dorsal and ventral lobe was (1.3±0.05), (0.88±0.03) cm respectively. The pancreas was a small organs in white-eared bulbul. The result of microscopic study that the pancreas in white-eared bulbul similar to other birds and covered by a thin C.T capsule with mesothelium cells. The pancreas parenchyma was consisted of exocrine and endocrine portions, the Langerhans island appeared in dorsal lobe in all histological sections which composed of different shapes and sizes. The intercalated ducts of ductal system lined by simple to low cuboidal cells then the epithelia changed to simple cuboidal in interlobular duct and become columnar in larger ducts. The main excretory ducts composed of three histological layers mucosa, muscularis and adventitia. | ||
