“…The acinar cells very rich with (rER) specially in the bottom of the cells and around the nucleus, these finding are in agreement with Stornelli et al, (2006) in Ostrich, Beheiry et al, (2018) in goose who establish that the abundant (rER) and Golgi complex were capable of secret a permanent amount of mucopolysaccharides forming a glycocalyx that supports the mucosal surface from the effect of pancreatic secretion.…”

“…These results are in agreement with Egerbacher and Bock (1997) who found many pleomorphic and enlarged mitochondria. The acinar cells contained proteases which are present as inactive zymogenic granules, in which this granules appeared in form of homogenous electron dense spherical material variable in size and scattered throughout the apical parts of the cells, Histological, Histochemical and Ultrastructure Studies on the Ostrich Pancreas 71 these findings are in agreement with Take et al, (2007) and Beheiry et al, (2018) in goose. Mescher (2010) confirmed that, every cell contained zymogenic granules which vary in its number as it decreased in samples collected after the meal.…”

“…The acinar cells appeared pyramidal having basally large vesicular nucleus with prominent large nucleoli which appeared spherical and electron dense, in contrast Simsek and Al-abay (2008) in quail and Beheiry et al, (2018) in goose distinguished the ultrastructure of some acini as an electron dense and the other as electron lucent in which the electron dense acinar cells contained electron dense cytoplasm and heterochromatic nuclei. The electron lucent acinar cells were less in number but active with euchromatic nuclei and prominent nucleoli.…”

“…The pancreas of the birds located on the right aspect of the abdomen and it is represented as an important mixed large gland related to the gastrointestinal tract (Deprem et al 2015;Beheiry et al 2018).The pancreas is bi-function gland, having the properties of endocrine and exocrine glands. The exocrine portion forms the majority of the pancreas, the acinar cells and its associated excretory ducts (Pieler & Chen 2006).…”

“…Moreover, the intralobular ducts which lined by simple cuboidal cells in both birds were found to be similar to that described by Şimşek and Alabay (2008) in Japanese quail, Al-Hathry (2000) in common quail; Al-Shaeli (2010) in duck; Faris (2012) in pigeon; Beheiry et al (2018) in goose. While in falcon, it is lined with simple squamous epithelium (Şimşek et al 2009) and with tall columnar epithelium in goose (Gülmez 2003).…”

The current study targeted to compare between the pancreas (exocrine part) of Japanese quail and Cattle egret. The pancreas was investigated in eight apparent healthy mature female Japanese quail and eight Cattle egret. Histological, histochemical, and ultrastructure studies were carried out. In both birds, the pancreas is located on the right side of the abdomen between the ascending and descending loops of the duodenum. The pancreas of the Japanese quail composed of dorsal, ventral, third, and splenic lobes, while in Cattle egret the pancreas is not lobulated. The Exocrine portion consists of serous acini and intercalated duct, intralobular duct, interlobular duct, and main duct. The duct system was similar in both birds with minor differences. The intralobular duct in the Cattle egret is characterized by the presence of serous glands within its wall. Under electron microscopy, the acinar cells were of two types, electron-dense, and electron-lucent acinar cells. Histochemically, the interlobular duct of the Cattle egret positively reacted to alcian blue (pH1) and aldehyde fuchsin stains but the interlobular duct of the Japanese quail was negatively reacted.

The present work was carried out to investigate the structure and ultra structure of the pancreas in the common pheasant (Phasianus colchicus). Totally, five healthy adult pheasant were used. The pancreas was assessed using histochemistry and transmission electron microscopy (TEM). The pancreas was composed of four lobes: dorsal, ventral, third, and splenic lobes. These lobes emptied into ascending duodenum through three excretory ducts as: ventral duct, splenic duct, and a common duct for dorsal and third lobes. The exocrine pancreas was constituted of pyramidal‐shaped acinar cells with aggregation of zymogen granules at their apical cytoplasm. The endocrine pancreas was identified as large islet of Langerhans as α islets and small islets as β ones. No mixed islet was observed. At the level of TEM, two types of acinar cells were distinguished: Dark cells with electron dense cytoplasm, and indented nucleus, Light cells with electron lucent cytoplasm, and regular nucleus. The α islets were mainly constituted by A and D cells, whereas the β islets principally contained B cells and a few A cells. No D cells were identified in β islets. B cells were characterized by their polymorphic granules which were surrounded by a narrow halo zone. The granules of D cells were quite different. These cells contained large spherical granules with lower density as compared to the A or B granules surrounded by a limiting membrane. In conclusion, the pancreas of the common pheasant has a species‐specific feature which must be considered in phylogenic studies.Research Highlights The common pheasant's pancreas was composed of four lobes as dorsal, ventral, third, and splenic lobe. There were three excretory ducts. Ventral duct for ventral lobe, a common duct for both dorsal and third lobes, and a distinct splenic duct for splenic lobe. The exocrine acini were composed of two distinct types of cells: dark cells and light cells. The large alpha islets were composed of alpha cells and a few numbers of delta cells and small beta islets were composed of beta cells and a few numbers of alpha cells.
