Abstract:
A study was conducted on histological studies on the trachea of black Bengal goat and garole sheep. Total ten samples were collected in each species from local slaughter house. In trachea the lamina epithelial was made up of pseudostratified ciliated columnar epithelium and cells were rested on distinct basement membrane. Goblet cells were predominant and variable numbers of migratory cells were observed within the epithelial layer. Lamina propria was found to be formed by loose connective tissue fiber. In case of sheep in between the lamina propria and submucosa a large bundle of muscle fibers was found towards the point of contact of two ends of the tracheal cartilage. The muscle bundle gradually diminish after traveling a certain distance from points of origin there after scanty muscle fibers was found all along the residual length of trachea and again towards the terminal portion of the tracheal ring gradually the width of the muscular layer is increased and width was highest at the point of tracheal cartilage. The numbers of the tubuloacinar glands were less as compare to goat.
