  the paired dorsal aortas running the embryo.

6

The amniotic cavity appears initially as a slit-like space within the:

  exocoelomic (Heuser’s) membrane
  extra-embryonic mesoderm
  ectoderm
  connecting stalk
  endoderm

7

Which of the following processes are necessary for the early development of the human embryo?
