Plate III. Reconstruction of the facial, glossopharyngeal and vagus nerve group in the 10 mm Human Embryo

Shown in Plate I, showing the series of motor nuclei of origin and the tractus solitarius. It can be seen how the latter is formed by the sensory roots on entering the marginal zone of the neural tube, analogous to the dorsal funiculi formed by the dorsal roots of the spinal cord. A section of the neural tube is included in the reconstruction to show its relation to these different structures. Ganglionic masses are represented by lighter shading than the fibre bundles, and the point at which the rootlets enter the neural tube is indicated by dark rings.

Enlargement about 35 diameters.

Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.     (More?

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.
