Fig. 29. Photomicrograph of section 344 of H1093 (22 somites)
Which passes horizontally through the segmental duct and the mesonephric vesicles.
In our specimens we find them to be continuous with each other and also with the nephrogenic bar, and that in the latter there are enlargements of the tissue with lumen inclosed at different regions. This latter phenomenon as seen in the 22-somite embryo (fig. 29) represents a series of vesicles without any interruption whatever. It is evident, then, that one has difficulty in following Felix and Watt in fixing any area along the nephrogenic tissue for the development of pro— and mesonephros with reference to the level of somites.

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.
