The pig embryo is presented in two ways: labeled and un-labeled. All of the sections are presented serially in an unlabeled fashion and then select sections have been labeled for you. The slides start from the crown of the pig embryo and proceed posteriorly towards the rump. The labels are color coded by system. Click on the system below to view the key for that system's labels listed in alphabetical order.
