Human Embryo Carnegie stage 11

Week 4 Carnegie stage 11 25 days, 19 somite pairs. This is a scanning EM of the embryo fractured to show the neural tube, notochord and somites.

Features shown include the surface ectoderm, neural tube, notochord, somites, somitocoels, dorsal aortas, and gastrointestinal tract.
