The main purpose of this study was to extend the microscopic investigations of the tracheal epithelium in the quail, in order to add some information on the fine structure of the luminal surface. Materials and Methods: The structure of the luminal surface of the tracheal epithelium of the quail was studied using scanning electron microscopy (SEM) and light microscopy (LM) histochemistry. Results: The pseudo stratified columnar epithelium composed mainly of ciliated cells and dispersed islands of single or groups of non-ciliated cells. The non-ciliated cells comprised a variety of basal, goblet cells and PAS positive cells exhibiting merocrine secretion. Conclusion: It was assumed that the tracheal epithelium of the quail closely resembles that of the chicken but the identity of the epithelial non ciliated cells still remains enigmatic as is the case with these cells of other bird species.]]>Cevik-Demirkan, A., R.M.
