Fig. 7. Sagittal Section of the Umbilical Region in an Embryo 7 mm in Length

This is a reconstruction from the Mall embryo No. 2. A detailed description of this embryo by Mall will be found in the Journal of Morphology, 1891, vol. v, p. 459.

The exoccelom in the cord contains the omphalomesenteric stalk, in the body of which are seen the omphalomesenteric vessels and the duct. The connection of the duct with the intestine has disappeared, but the duct still persists in the cord and shows a bulbous dilatation at its proximal end. If it still persists in later life, we shall have a cyst in the abdominal wall or in the structures of the umbilicus. The junction of the superior mesenteric vein with the omphalomesenteric vein is clearly seen in the mesentery.

Historic Disclaimer - information about historic embryology pages

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?
