The sebaceous gland is part of the holocrine glands (glands that release entire cells filled with secretory products). The cells of the sebaceous glands produce globules of a fatty material that accumulates, causing the cells to swell and burst. The resulting mixture of fatty material and cellular debris is called sebum.
