Human embryo

Stage 9 day 20, somites 3-4

Ventrolateral view (cut chorionic) showing the embryo, yolk sac and amniotic sac.

Note:

  1. the relative size of the embryo and the associated extra-embryonic coeloms.
  2. the shape of the early folded embryonic disc and rostro-caudal bendings.
  3. the caudal attachment of the embryo to the chorionic wall.
  4. the relative thicknesses of the embryo and extra-embryonic membranes.
