Fig. 21. Junction of the maternal and fetal tissues

21 This photomicrograph shows the junction of the maternal and fetal tissues. The edge of the maternal tissue is indicated by the termination of the reticular f~'ramework. The reticulum is frayed and irregular. Numerous strands project freely into the implantation cavity. There is clumping and irregula1'ity of pattern of the reticular frmliework. The syncytial cell mass has phagocytized some reticular strands and continuity between the reticulum and these strands is demonstrated. Bielschowsky-Maresch teclmique. X 790.

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?
