Histomorphometric and Histochemical Finding of the Proventicular and Ventricular Stomach between the African Grey Parrot (Psittacus erithacus) and Black Francolin (francolinus) in South Iraq
Keywords:Francolin, Parrot, proventriculus, ventriculus, histochemistry
The study was done on sixteen specimens including: eight Parrot and eight francolins of both sexes.
The current study aims to discover the structures of proventiculi and ventriculi belonging to these birds
specifically their histologic and histochemical textures. The anatomical studies revealed that stomach of both
birds consists of: proventiculi & ventriculi. Histological exam was showed that the wall of proventiculus of
the Parrot and francolin composed of four layers including: mucosa, submucosa, muscularis and serosa. The
epithelia of proventiculi and venticulus were simple columnar cells for each bird.
The obtained means of thickness of layers of proventiculus and venticulus appear different between male
and female of both birds.
For histochemical studies there were some different reaction of PAS- stain which were detailed in the results.
