Plate II. Median view of a model of the cranial nerves in the 10 mm Human Embryo

Shown in Plate 1. A portion of the spinal cord is represented and above that everything is cut away, excepting the sensory bundles and motor nuclei of the different nerves, together with that portion of the marginal zone which is to form the funiculus anterolateralis. The somatic motor nuclei are colored red, and it can be seen that they form a column that is practically continuous with the cells of the ventral horn of the spinal cord. Enlarged about 30 diameters.

The author suggests an "estimated age is 31 days", that would be Carnegie stage 14. The appearance of the upper and lower limb buds are more like a later Carnegie stage 16 embryo occurring in week 6, 37 - 42 days, CRL 8 - 11 mm.
