Fig. 21. Schematic Transverse Sections of two Human Embryos

A In the 3rd. week of development. B In the 4th week of development.

The numbers are placed on corresponding points : Epiblast, shaded ; hypoblast, black ; mesoblast, stippled.

1. Neural groove and canal.

2. Epiblast of embryo.

3. Epiblast lining amnion. Only the attachment of the amnion is represented in B.

4. Paraxial mesoblast.

5. Intermediate cell mass.

6. Coelom, bounded by the somatopleure externally and splanchnopleure internally.

8. Mesoblast on amnion.

9, 10. Chorion.

11. Notochord.

12. Archenteron.
