We then used the sequence of images of an embryo to make a QuickTime digital movie. After we made movies of several serially sectioned frog and chick embryos, we started using them in our developmental biology labs. Students like watching and using these QuickTime movies to learn about developing embryos, and we want to share these movies with other students of developmental biology. If you want to use these movies in your classes, you can download the full-size QuickTime movies of these embryos. When we study embryology, we need to visualize the changes that occur in developing embryos.
Direct observation is the ideal method for visualizing developing embryos.
Everyone enjoys watching living embryos develop or watching time-lapse movies of developing embryos. Some embryos remain transparent throughout their development and we can see what's going on inside and outside at the same time. To see what's going on inside, we typically cannot dissect an embryo because it's too small. We have to look at serial sections of embryos. Serial sections are where we slice an embryo as if it was a sausage.
