A cilium is a microscopic hair-like process extending from the surface of a cell. Capable of rhythmic motion, it acts in unison with other cilia to cause the movement of the cell or the surrounding medium.

Many epithelial surfaces in the body are ciliated - covered in cells which contain tiny hair-like structures beating in synchrony to move secretions or objects around. Examples include the respiratory tract where ciliated cells in the mucous membrane sweep clean dust and germs trapped in mucus. Another example of ciliated cells is in the fallopian tubes which move the ova from the ovary to the uterus.
