In this Live lecture, I will discuss in detail the two events that occur during the process of gastrulation: creating the primitive streak in creating the three germ layers. I will also talk about a Pathological condition (teratoma) related to failure of the primitive streak's complete regression.
WARNING: there are real pictures of teratomas that may be disturbing for people who are sensitive to seeing human pathology. Please don't watch that section of the video if you're sensitive.
