Tracings of serial histological sections from 4 human embryos at
different Carnegie stages were used to
create 3-dimensional (3D) computer models of the developing heart. The
models were constructed using
commercially available software developed for graphic design and the
production of computer generated
virtual reality environments. They are available as interactive objects
which can be downloaded via the
World Wide Web. This simple method of 3D reconstruction offers significant
advantages for understanding important events in morphological sciences.
