I am finishing up my Embryology lectures which makes me sad. The subject is confusing making it very intriguing.
Today's tutorial couldn't have been any better. One of the academics puts together the most informative and well-constructed practicals. To wrap up all we learned about embryos, the practical had us view 3D slides. They are an entirely different cup of tea. Very hard to draw and decide what one is looking at. On top viewing microscope slides, I got to dissect a fertilized chicken egg! As the picture shows, the top of the shell was tweezed away to reveal the inner air pocket. My subject was right underneath the membrane. The chick embryo rights itself with gravity because in the nest the top of the egg is the warmest closest to the hen. If I can figure out how to post a video, I recorded the heart beating. A little red spec moving back and forth in the clear embryo. Even at that tiny, the blood is flowing. The embryo had to be cut out of the membrane and off of the yolk. I moved it to formlin to set the cells, unfortunately this kills the poor chick. He was a good teacher.
On the right is a picture of the entire embryo with the vascular ring. The microscopes were not high powered to view intense detail but I could judge the age and see the larger structures. It was amazing!
