Accepted Answer

Hello everyone. Our next question says which one of the following is developed from the arken theron. And the ark N. Tron occurs after gas relation. That's when our embryo goes from the hollow single layer blastocyst and develops into this multi layer gasparilla. And the ark N. Tron. Is this interior space with an opening to the outside. That is going to become the sort of the primitive gut. It's going to become the digestive system, It's opening that can develop into the mouth. So let's look over at our choices. We have um Choice A. Which is the ectodermal. Well the extra term is actually this outer layer here. So the inner cavity here is not going to become an outer layer. So we can eliminate Choice A. Choice B says the lumen of the gut lumen is just a term for the inside of a tribute structure. So that is a good description actually of what the this arken tron. This cavity will become the interior of the gut. So Choice B is correct. Just look down at our final choices here. Choice. See the placenta. Placenta doesn't even exist in this very early stage of embryonic development. So we can eliminate choice C. And choice D. The brain. Well, the nervous system develops from the ectodermal outer layer. So it is not going to come from the ark antron. So we can eliminate choice D. Thanks for watching. See you in the next video
