An oil gland is a sebaceous (or sebiferous) gland that secretes sebaceous matter. Oil glands are part of the body's integumentary system and serve to protect the body against germs. They are mainly situated in the corium or true skin. True oil glands secrete matter through a duct. Many creatures, such as fish, e.g., have oil glands. In mammals they serve as a protectant and lubricant for hair and skin. In birds it is located at the base of the tail, which also supplies oil that is spread upon the feathers during preening.

Famous quotes containing the word oil:
“Opinions are to the vast apparatus of social existence what oil is to machines: one does not go up to a turbine and pour machine oil over it; one applies a little to hidden spindles and joints that one has to know.”
—Walter Benjamin (1892–1940)
