This project looks for through the preparation of a didactic component, in the area of the embryology, facilitate the learning of this area, for like this attain solidify the foundations of the development , with the purpose to improve the knowledge, the capacities and the aptitudes of the professionals in this field. The development of the posed bases mainly in the harvest of foetus of different ages gestation for realisation of one guides type atlas of the fetal development.
