“…Regarding the histochemical examination of the proventricular submucosal glands, the current results showed the supra‐nuclear apices of the epithelial cells lining the compound tubuloalveolar glands’ ducts were reacted intensely with PAS stain and negatively with AB stain, while those of the secretory portions, oxynticopeptic cells, were negatively stained with both stains. This result was in accordance with Zaher et al (2012), Hamdi et al (2013) and Udoumoh and Ikejiobi (2017). However, it was not consistent with that noticed by Zhu (2015) who reported that the cells lining the compound tubular glands’ ducts contain a mixture of acidic and neutral mucopolysaccharides, and Chikilian and Speroni (1996) in tinamou, who detected a moderate amount of glycoprotein in the epithelial cells of the glandular secretory portion.…”

“…These results were in harmony with the results of Sayrafi and Aghagolzadeh (2019) who reported that the proventricular glands were of simple tubular type in the cranial portion, and branched tubular in the remaining portions, while the deep proventricular glands were compound tubuloalveolar. On the contrary, Udoumoh and Ikejiobi (2017) in African pied crow and Zhu et al (2013) in the yellow‐billed grosbeak reported that the proventricular glands were only compound tubular.…”

“…Furthermore, Hodges (1974) documented that the negative reaction of oxynticopeptic cells to PAS and AB indicated that these cells have no mucous secretory function as they secrete HCl and pepsin. However, Bansil and Turner (2006), and Udoumoh and IKejiobi (2017) reported that the secreted ductal mucin acts as a mucosal surface lubricant and shares in their protection from the physical injuries of the luminal contents.…”

The hooded crow (Corvus cornix) belongs to the order Passeriformes (family Corvidae: genus Corvus, species C. cornix). These species are classified as omnivorous birds that feed on grains, seeds, fruits, insects, reptiles and small birds, and they are distributed in Eastern and Northern Europe, and the Middle East (Hutchins et al., 2002).Anatomically, the avian stomach is composed of two definite compartments: the proventriculus and the ventriculus "gizzard" (Saran & Meshram, 2020). Both parts are morphologically and

“…The deep proventricular glands in the starlings were of the compound tubuloalveolar type, which in this respect corresponded to the study of Ogunkoya and Cook (), in three species of passerines. In the red jungle fowl, the glands were a type of tubuloalveolar (Kadhim et al, ), but these glands in the yellow‐billed grosbeak and African pied crow were seen as compound tubular glands (Udoumoh & Ikejiobi, ; Zhu et al, ). Cells lining the compound tubuloalveolar units of the proventricular glands showed a dentate appearance; similar findings were achieved by other researchers (Kadhim et al, ; Zhu et al, ).…”

“…These findings were consistent with the results of Selvan et al (), in guinea fowl. In addition, Udoumoh and Ikejiobi () reported that the compound tubular glands of the proventriculus of the African pied crow exhibited PAS‐negative reaction, but the collecting duct and the collecting tubules demonstrated PAS‐positive reaction. However, the presence of mucin protects the mucosal surface as a lubricant and forms a resistant mucosal barrier to the physical damage by the luminal contents (Bansil & Turner, ; Udoumoh & Ikejiobi, ).…”

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.

The present investigation was performed to transpire the celiac artery distribution, histological, and histochemical characteristics of the proventriculus in eight adult barn owls (Tyto alba) of both sexes. Six birds were subjected to anatomical investigation of the celiac artery distribution and two owls were used for routine histomorphological techniques. The proventricular length, width, and lumen diameter were measured at 14.18 ± 0.08, 6.46 ± 0.17 and 1.46 ± 0.14 mm, respectively. The celiac artery in barn owl gave off six collateral arteries before its division into right and left branches. The arteria hepatica dextra does not originate from the right celiac division. Unlike other birds, there were left dorsal and left ventral gastric arteries. Histologically, the proventricular wall consisted of main four tunics. The lining epithelium is simple columnar with plicae and sulci. The muscularis mucosa is absent. The submucosal gastric glands were in two rows in the cranial proventricular portion while were arranged in one parallel row in the middle and caudal portions with pear-shaped, oval to round tubuloalveolar lobules. The mucosal folds, tubular mucosal glands, tubuloalveolar lobules, and their mucus secretion in the collecting ducts were positively reacted to PAS and alcian blue stains. The interlobular collagen fibers, elastic fibers, and reticular network were intensely reacted to Masson’s trichrome, Orcein, and Gomori's reticulin stains, respectively. These anatomical and histomorphological features of the barn owl proventriculus were aimed to provide recent data comparable with most species of birds and the presence of diversity that might be attributed to their feeding demeanor.
