Federative International Committee on Anatomical Terminology hold periodic meetings in different countries on a rotating basis, where they study morphological terminology: anatomical, histological and embryology of the human being. The results of this committee were published in 1998 in the anatomical area and in 2008 in the histological area. It is currently working in the embryologist area. The main objective is to study the problem of morphological terms and its possible solutions. The aim is to achieve a common scientific language that allows international integration, facilitating scientific exchange and progress in the various medical specialties. This impacts on research, teaching and medical care worldwide. Federative International
