Human Embryo (Carnegie Stage 10)

Scanning electron micrograph dorsal view of Carnegie Stage 10 human embryo. This dorsal view of the early embryo mainly shows the neural groove before its closing to form the neural tube, the precursor of the spinal cord and brain.


  • Week 4, 22 - 23 days, 2 - 3.5 mm, Somite number 4 - 12
  • Neural groove forming from neural plate on upper surface.
    • large brain fold region to top of image.
    • narrow spinal cord region to bottom of image.
  • Heart bulge can be seen on right ventral surface.
  • Connecting stalk to the bottom of the image.
  • Amniotic membrane cut edge shown at edge of developing embryo.
