Abstract

The present study was conducted on the gross and histomorphological structure of isthmus in indigenous chicken of Assam. The isthmus was short narrow and partially tortuous tube. The line of demarcation between magnum and isthmus was marked by sharp narrow band of tissue. The lamina epithelialis mucosae were lined by simple ciliated columnar epithelium and the lamina propria submucosae was composed of distended branched tubulo-alveolar gland with loose connective tissue. Tunica muscularis consisted of inner circular and outer longitudinal layers of smooth muscles fibres and tunica serosa was composed of loose connective tissue. The isthmus exhibited PAS positive reaction at the cytoplasm of aggregated clusters of cells located at the folds and in the lamina epithelialis mucosae, lamina propria-submucosa and blood vessels and muscles.
