Depending upon which layers of the structure are involved, they are described as being either true or false. In medicine, the term usually implies the structure is not normally present. However, in the embryonic stage, some normal structures begin development as a diverticulum arising from another structure, such as the thyroid diverticulum that arises from the tongue.
