MORPHO-HISTOLOGICAL AND HISTOCHEMICAL STUDY OF THE GALL BLADDER OF WHITE – EARED BULBUL (Pycnonotus leucotis)

Abstract

The present work aims to study the morpho-histological and histochemical structure of gall bladder in white – eared bulbul (Pycnonotus leucotis) in college of veterinary medicine at university of Basrah. Fifteen samples of adult healthy males were used, which divided in to three groups. Each group include (5) male used for this study. Tissue sections stained with H&E, Mallory’s, PAS, Verhoeffs and Toluidine- blue. The result indicated that the gall bladder was appear to have blind ovoid- shaped with green color and situated in the middle ventral surface of the right lobe of the liver. The histological examination revealed that it consists of three layers (tunica mucosa, tunica muscularis and tunica serosa or adventitia).
