The Visible Embryo is a visual guide through fetal development from fertilization through pregnancy to birth. As the most profound physiologic changes occur in the "first trimester" of pregnancy, these Carnegie stages are given prominence on the birth spiral.
The shape and location of embryonic
internal structures and how they
relate and are connected to each
other is essential to understanding
human development. Medical
professionals create a mental picture
of this process in order to determine
how well the fetus is progressing. It is
also the basis of knowing how and when
errors in development occur and if a
possibility exists for a corrective
It is equally important for expectant
parents to understand the relationship
of these internal structures and how
their infant develops through pregnancy.
Creating the images for The Visible Embryo, included capturing data from slides and three dimensional structures on fetal anatomy in The National Institutes of Health, Carnegie Collection of embryos, as well as from 3D and 4D ultra sound images.
