“…Our observations regarding the tunica submucosa were consistent with those of Hassan and Moussa () and Kadhim et al (), showing that the tunica submucosa was a narrow connective tissue layer sandwiched between the main mass of the lamina muscularis mucosae and the inner layer of the tunica muscularis. Our results were also consistent with Ogunkoya and Cook (), indicating that the submucosa of proventriculus in the three species of Australian passerines had no proventricular glands.…”

“…In the present study, the lamina muscularis mucosa was observed as a thin layer in the proventricular mucosal tunic, surrounding the lobules of the tubuloalveolar glands. In accordance with the results of this study, in the study of Hassan and Moussa (), proventricular glands in pigeon and duck were surrounded by muscle fibres branched from the lamina muscularis mucosae. However, the proventricular glands in pigeon and duck were situated between the inner and outer layers of the lamina muscularis mucosae.…”

“…The mucosal epithelium of the proventriculus of starling was lined by a simple columnar epithelium, and this is similar to the findings of other studies in many bird species (Hassan & Moussa, ; Kadhim et al, ; Ogunkoya & Cook, ; Selvan et al, ).…”

“…Current observations revealed that the wall of the proventriculus consisted of four tunics, namely tunica mucosa, tunica submucosa, tunica muscularis and tunica serosa. This structure was documented in the proventriculus in many avian species such as duck and domestic pigeon (Hassan & Moussa, ), guinea fowl (Selvan, Ushakumary, & Ramesh, ) and red jungle fowl (Kadhim, Zuki, Noordin, & Babjee, ). Whereas, in the wall of the proventriculus of yellow‐billed grosbeak (Zhu, Wang, Shi, Hu, & Chen, ), only three tunics were observed in which only tunica mucosa, muscularis and serosa were detected.…”

The histological and histochemical structures of the proventriculus of starling (Sturnus vulgaris) were examined using haematoxylin and eosin and special staining, that is periodic acid schiff (PAS), Masson's trichrome, Alcian blue, Orcein and Reticulin. All three cranial, middle and caudal parts of the proventriculus were also studied. The study results showed that the wall of the proventriculus consisted of mucosal, submucosal, muscular and serosal tunics. The mucosal tunic presented folds and sulci on its luminal surface. In the first third of the proventriculus, the tunica mucosa characterized by presence of folds lined by stratified squamous epithelium and presence of simple tubular glands in the lamina propria. In the middle and caudal thirds of the proventriculus, the surface was covered by a columnar epithelium, and the branched tubular glands were extended through the lamina propria. From the base of the branched tubular glands, the deep proventricular glands were observed that were compound tubuloalveolar lobules. The surface epithelium of the tunica mucosa and the cells lining the proventricular glands showed a positive reaction to PAS and Alcian blue stainings. In addition, the epithelial cells of the tubular and branched tubular glands showed Masson's trichrome‐positive reaction. The submucosal tunic was thin in the proventricular wall. The tunica muscularis was formed by a thin inner layer of longitudinal smooth muscle fibres and a thick outer layer of circular fibres. The serosa consisted of loose connective tissue, rich in blood vessels and covered by mesothelium.

A focus on the gross morphological and ultrastructural characteristics of the oesophagus and stomach of Eurasian common moorhen (Gallinula chloropus chloropus, Linnaeus 1758)

The present work was the first attempt to examine the oesophagus and stomach of the Eurasian common moorhen grossly and by SEM. The oesophagus was composed of long cervical and short thoracic parts. The longitudinal folds of the cervical part were narrower than that of the thoracic part, while the depressions between these folds were shallower and wider in the cervical part. On the epithelial surface of the oesophagus, micropapillae were present and they were numerous and smaller at the level of the cervical part. The openings of the oesophageal glands were circular at the level of the cervical part and oval to elliptical at the thoracic part. The crop was absent. The proventriculus was fusiform in shape; its mucosa was arranged in several, concentrically arranged mucosal folds connected with each other by transverse folds. The proventriculus glands were oval and opened by raised papillae on the epithelial surface. The gizzard was oval; its mucosa was lined by a horizontal layer of cuticle appeared like the fish scales, while the vertical part of the cuticle appeared as thin rods. The folds of the oesophagus are functioning for the expansion for the passage of the food particles. The tunica musculosa of the gizzard was thick to help in grinding of the food particles.

We describe the functional morphology of the digestive tract of the Eurasian collared dove, Streptopelia decaocto using anatomical, morphometric, histological, histochemical, and ultrastructure techniques, and relate our findings to the species' dietary niche. Our results revealed that the esophagus is displaced on both sides of the neck and has highly folded tunica mucosa, which confer greater elasticity for efficient swallowing and passage of food to the crop. The proventriculus is delicate and its mucosal layer contains polymorphic glands with dense profound and superficial secretory units that open to the luminal surface by gastric pores. The ventriculus is biconvex and lined with a keratinized koilin membrane. The tubular glands within the mucosal lining include the isthmus, the neck, and the basal segment that comprise chief and basal cells with prominent nuclei. At the cuticle-mucosal interface, pyramidal vertical rodlets of the cuticle are secreted and superficially covered by a thin film of a horizontal matrix. The mucosa of the ileum form pyramidal villi that are oriented perpendicularly to the central lumen. Enterocytes infiltrated with goblet cells make up the epithelial lining of the villi. There are subtle differences in the thicknesses of corresponding tunics together with histochemical reactions of alcian blue (AB) and Masson-Goldner trichrome (MT) for their microstructures. Overall, our findings reveal remarkable convergence of both macro-and microstructures in S. decaocto to other granivorous species, and offer further evidence of the close association between functional morphology and feeding style relative to food swallowing, digestion, and absorption.

Gross and Microscopic Studies on the Stomach of Domestic Duck (Anas platyrhynchos) and Domestic Pigeon (Columba livia domestica)

Abstract: Ten adult domestic Mallard ducks and ten adult domestic pigeons of both sexes were used for morphologic and histological study. The proventriculus was the last part of the foregut. It was cone-shaped in pigeon while it was tubular in duck and arose from the esophagus. The
