Stages of Fertilization and the Development of the Embryo, 2-times magnified
The model illustrates schematically how the ovum matures, how ovulation and fertilisation occur and how the fertilised ovum develops to the stage where it embeds itself in the womb wall to begin the growth into an embryo.
The various stages are shown in larger-than-life model form in an ovary, fallopian tube and womb. An even more enlarged illustration of each is also printed on the base. Supplied on a base.
