“…The splenic lobe was seen as a curved process of the dorsal lobe. This result was consistent with those described previously in the quail (Simsek et al, 2008), chickens (Rawdon, 1998), goose (Gülmez et al, 2004), red jungle fowl (Kadhim et al, 2010), Palm dove (Saadatfar et al, 2011), andduck (Al-Shaeli, 2010). The third lobe can be considered as a component of the ventral lobe (Mikami & Ono, 1962) and maybe absent in many avian species such as Guineas fowl, common gull (Hamodi et al, 2013), and bustard (Bailey et al, 1997).…”

“…The pancreatic parenchyma of the common pheasant was divided into exocrine and endocrine portions. These findings agreed to other domestic and wild birds (Al-agele & Mohammed, 2012;Al-Haaik, 2019;Beheiry et al, 2018;Gülmez et al, 2004;Hamodi et al, 2013;Helmy & Soliman, 2018;Saadatfar & Asadian, 2009;Saadatfar et al, 2011;Simsek et al, 2008). The exocrine pancreas was constituted of spherical acini units with pyramidal cells.…”

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.

“…The architecture of the lovebird pancreas stands out as a harmonious blend of specialized compartments. The enveloping CT capsule, along with the partitioning of the exocrine pancreatic tissue into lobules, is consistent with the typical organization previously documented in domestic and wild birds (Al‐Haaik, 2019; Beheiry et al., 2018; Gulmez et al., 2004; Hamodi et al., 2013; Helmy et al., 2018; Saadatfar & Asadian, 2009; Saadatfar et al., 2011; Simsek et al., 2008). The presence of acinar units, each having diverse shapes and sizes, reflects the secretion of known digestive enzymes (Watanabe et al., 1975).…”

BackgroundLovebird (Agapornis personatus) is a monotypic species of bird of the lovebird genus in the parrot family Psittaculidae and order Psittaciformes.ObjectivesThe present study was designed to investigate the histology and immunohistochemistry of the pancreas in the lovebird.MethodsTotally, three adult birds were used. The pancreas was assessed using histological and immunofluorescent staining to detect insulin, glucagon, somatostatin, pancreatic polypeptide (PP) and neuropeptide Y (NY).ResultsThe exocrine pancreas was composed of pyramidal acinar cells with zymogen granules at the apical cytoplasm. The endocrine pancreas was identified as large alpha, small beta and mixed islets of Langerhans. No intercalated duct was observed. Alpha cells with a density of 28.55% were the most numerous cell type, which were populated throughout the large islets, especially at the periphery. The beta cells with a density of 15.78% were accumulated mostly at the periphery of islets. The delta cells exhibited 17.81% intensity. Despite their lower density, the distribution of delta cells was like that of A cells throughout the islets. PP and NY cells were distinguished with densities of 14.69% and 20.63%, respectively.ConclusionsAlthough the arrangement of acinar cells, ductal systems and endocrine islets reflects patterns observed in various avian species, the absence of intercalated duct, the presence of three types of Langerhans islets as alpha, beta and mixed islets and the high expression of NY in the islets were some unique features observed in the current study. These findings contribute to the broader understanding of avian pancreas histology.

“…These findings are consistent with one another. Acini with an oval shape were discovered by [19] in the Palam dove. These acini included cells that were either pyramidal, tall columnar, or rectangular in shape, and they were arranged in a single layer.…”

One of the organs that can be found in the abdominal cavity is called the pancreas. It is a vital component in the process by which the food we eat is transformed into fuel for the cells of the body. For investigation of morphological description of the pancreas, the study was performed on twenty adult swan geese (10 males and 10 females). According to the morphological findings, the pancreas of geese was located on the right side of their abdominal cavity. It possessed four lobes—dorsal, splenic, ventral, and third and a distinctive duodenal papilla. It was between the ascending and descending duodenal loops. The goose pancreas has a thin covering of connective tissue over its mesothelium. The pancreatic parenchyma was divided by connective tissue septa, into numerous lobules, and these lobules extended outward from the pancreatic capsule. There was a wide range of diameters for the blood vessels. It consists of significant blood arteries, which can be identified by their oval or circular, bright nuclei. They have oval or circular, brilliant nuclei with the nucleolus. In the swan goose, serous acini and islets of Langerhans made up most of the pancreatic parenchyma. Exocrine cells had pyramidal shapes, acidophilic granules, and serous acini. In conclusion, the pancreas of geese like the most bird and is different from domestic animals.
