Human Embryo Stage 8
- Scanning EM dorsal view (cut amnion) showing detailed view of the prechordal region.
- Carnegie stage 8, day 18
- Selected region from the image selected rostral (cranial) region, which is in turn the rostral region of the entire embryonic disc image.
- Note the rostro-caudal axis (top to bottom), the growing brain region of the neural plate (top) and shape of the folding embryonic disc.
Primitive node and streak still visible below the region where the posterior (caudal) neuropore will be located.
Note the cut edge of amniotic sac with two layers (inner ectoderm, outer extra-embryonic mesoderm)
