Fig. 13. Sagittal Section of the Umbilical Region in a Human Embryo 4.5 cm in Length
The intestine has receded completely into the abdominal cavity. The exoccelomic cavity, although small in size is still clearly recognizable in the cord, where it shows spindle-shaped dilatations. It now contains only the omphalomesenteric vessels, which have become embedded in its wall. The allantois (urachus) is the distal prolongation of the urinary bladder, and shows already the characteristic dilatations noticeable in older embryos and occasionally found after birth. The structures of the cord show the characteristic twisting of the embryo to the right.

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.
