Histological and Histochemical description of the pancreas in Gallus gallus Domesticus

In birds, the pancreas is crucial for both endocrine and digestive control. Understanding the avian pancreas' glandular makeup and functional secretion patterns is aided by histological characterization. The purpose of this study was to examine the histological architecture of the pancreas in Gallus gallus, with a focus on the identification of exocrine and endocrine components, glandular organization, and secretion types. Standard histology procedures were used for the collection and processing of pancreatic samples from five Gallus gallus domesticus. To examine cellular and glandular features under a microscope, tissues were fixed, embedded in paraffin, sectioned, and stained using histological dyes. A well-developed exocrine section made up of acinar cells with granular cytoplasm suggestive of serous discharge was seen upon histological inspection. the islets with different cellular distributions served as a representation of the endocrine component. Mixed glandular activity and distinct endocrine and exocrine area differentiation were noted in the study. The studied Gallus gallus species' pancreas exhibits a complicated histological architecture with two functioning components. These results serve as a guide for next comparative research and advance anatomical and physiological knowledge of hormone and digestion regulation.
