This picture is my drawing about germ layer - not embryonic folding as I wrote initially.

enter image description here

Where exactly is the endoderm here in the picture?

The known things

  1. Ectoderm
  2. Neural tube
  3. Notochord
  4. Endoderm - Where is this?
  5. Somite
  6. Somite leg
  7. Intraembryonic coelom
  8. Embryonic somatopleura
  9. Embryonic splanchopleura (lateral mesoderm)
  10. Endoderm
  11. Mesoderm (intraembryonic)

Ok so that's not the best picture, but I think it would be along the bottom of the top wall there. Want to give us a few clues with the parts you're sure of? –  Atl LED Feb 20 at 14:45
    
Another strong possibility is that you're missing it in the inside of 2. –  Atl LED Feb 20 at 14:55
    
@AtlLED I added clues to the body of the question. –  Masi Feb 20 at 15:08
    
umm... you do note you have endoderm twice, once as 10... –  Atl LED Feb 20 at 15:19
    
Again you may or may not want to further clarify what slice and when in the germ layer you are looking (might make this a better question). After thinking about it, I think you were going for neural tube and chorda formation (which is exactly what I DDG'ed to pull that image). –  Atl LED Feb 20 at 15:34

I think you're going for a view of tube formation, in which case, here's a good image:

enter image description here

  1. Lateral plate mesoderm
  2. Intermediate mesoderm
  3. Somite mesoderm
  4. Chorda
  5. Endoderm

Again in your drawing I think you correctly have it labeled as 10, and don't really need to put it twice.

Thank you! Of course, I had mistake in numbering and then started to think where the missing number should be, since all known parts were already taken. –  Masi Feb 20 at 16:03
