The Histological Study of Proventriculus Stomach in Iraqi Black Francolin (Francolinus francolinus) and Common Teel (Anas Crecca)

Abstract

Six adult of black Francolin and six of adult of common Teel were prepared for the histological study of true stomach. The samples from proventriculus of two birds which stained with routine staining by hematoxylin and eosin. The wall of proventriculus in two types of birds consists of four layers or tunics: the first was tunica mucosa had longitudinal folds and lined by simple columnar epithelium. The lamina propria contained simple tubular gland, the super facial gland in Common Teel was longer than in the black Francolin. The tunica sub mucosa contained compound tubular gland, the tunica muscularis in the in both species was consist of two type of smooth muscles inner, circular and outer longitudinal the tunica musculris in black Francolin were thicker than in the Common Teel the tunica serosa in the both species about loss connective tissue contained blood and lymph vessels.
