Human embryo

Stage 9, day 20, somites 3-4

Scanning EM lateral view (cut away from amniotic sac and yolk sac) showing the embryo and connecting stalk.

Note:

  1. the relative size of the embryo.
  2. the shape of the early folded embryonic disc and rostro-caudal bendings.
  3. the size and shape of the brain fold region.
  4. the primitive node and streak (left) beside connecting stalk.
  5. the position of the prechordal plate (cardiogenic region) ventral to brain fold.
