The outer layer of cells will form the placenta, and the inner cell mass will form the fetus. I'll draw it kind of all coiled back here. And once the sperm can deliver its genetic material beyond that, fertilization has occurred. This is the zona pellucida that we talked about earlier. This is a pretty bare bones cell. Sperm binds to the zona pellucida, the glycoproteins, you have an acrosomal reaction, and then a cortical reaction prevents more than one sperm getting in.
