Mucous Membrane. Under the term mucous system anatomists include the skin, mucous membranes, and true glands, all of which are continuous with one another, and are essentially composed of similar parts (see SKIN, GLANDS). The mucous membrane is divided into the alimentary mucous membrane (for which see DIGESTION, Vol. III. p. 813), the respiratory (see NOSE, RESPIRATION), and the genito-urinary (see KIDNEYS, &c.).
