Carnegie Stage 14

The movies below show anatomical domains defined in the A386 and N420 models. The domains have been manually defined in the OPT models using specialised software and then visualised using commercial rendering packages.

The various domains are: neural tube - orange; heart - red; liver - dark green; optic vesicle - dark blue; otic vesicle - yellow; dorsal root ganglia - cyan.
