Which tissues will contribute to the chorion?
I have an exercise asking me to choose two letters (from this diagram: http://bayimg.com/iAlPHAAeL) that indicate the layers that will contribute to the chorion.
As far as I understand, the chorion consists of the extraembryonic mesoderm and the trophoblast.
My issue is I can't see any extraembryonic mesoderm on this diagram...?
Any help would be great!
Thanks in advance.
