A '''frenulum''' (or '''frenum''', plural: '''frenula''' or '''frena''', from the Latin ''frēnulum'', meaning "little bridle") is a small fold of tissue that binds movable structures to non-movable structures in the body. In the human body, examples of frenula include the frenulum linguae, under the tongue, the frenulum labii superioris inside the upper lip, and the ''frenulum labii inferioris'' inside the lower lip. The word ''frenulum'' on its own is often used for the frenulum in the human penis, which is an elastic band of tissue under the [[glans penis]] that connects to the [[foreskin]] to the vernal mucosa, and helps contract the prepuce over the glans. This is sometimes colloquially known as the "banjo string".
