Fig. 3. Median sagittal section of embryo, yolk-sac, body-stalk, allantois, and adjacent chorion

Slightly schematized, about X 40. The primitive streak and head process are represented as if both lay in the same plane. The chorionic villi are quite diagrammatic, their connections with each other not being indicated. Two "funnels" in the bodystalk, further details in text. Marginal lines as in fig. 2.

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?
