This study was accomplished to investigate the ultrastructure of mucous glands in dorsal skin of frog (Rana catesbeiana) by means of scanning and transmission electron microscopes. The dorsal skin of Rana catesbeiana is composed of epidermis and dermis. The cutaneous mucous glands consist of inner glandular epithelial cells and outer myoepithelial cells. Glandular epithelial cells are divided into four types by the microscopic ultrastructure; ER-rich cell, round secretory granule-containing cell, foam-like granule mass-containing cell, mitochondria-rich cell. Myoepithelial cell has a long elliptical nucleus and filled with fibrous materials in the cytoplasm. As a result of scanning microscopic observation, the surface of dorsal skin is covered with cutaneous protrusions. The opening sites of the mucous glands are irregularly distributed in dorsal skin.
