This video shows the process of gastrulation, in which the bilaminar embryonic disc undergoes reorganization to form three primary germ layers. Note: Our anatomy team is aware of the left and right labelling issue at 1:06 – the labels should be the other way around. Thank you to anyone who provided feedback on this error. Our team is currently working to resolve it, and we will provide a link to an updated movie as soon as possible.
