Fig. 19. Intra-abdominal View of the Umbilical Region in a Human Embryo 10 cm in Length

(X 6.)

The urachus is very narrow, but is continued out into the cord (allantois). In this cross-section of the cord it was recognized as a nest of polygonal cells devoid of a lumen, and surrounded by several bundles of well-defined non-striped muscle. This muscle surrounded the urachus down to, and merged into, that of the bladder. The umbilical ring is completely sealed over by a broad connective-tissue band. In the cross-section of the cord no remnants of the exocoelomic cavity were demonstrable, but in its place were traces of blood-vessels, evidently remains of the omphalomesenteric vessels.
