Comparative Histology and Micrometric Analysis of Pharyngeal cavity in Egyptian Laughing Dove (Streptopelia senegalensis aegyptiaca) and Japanese Quail (Coturnix coturnix japonicum)

Birds of different families; Japanese Quail (family Phasianidae) and Laughing Dove (family Columbidae) were used for this study to focus on the histological and micrometric comparison of the pharyngeal roof and floor with its content. The thickness of the lining epithelium of the pharyngeal roof,...
