Fig 6. Portion of the chorionic wall shows two short villi

6 This portion of the chorionic wall shows two short villi with mesodermal cores. The Langhans cells extend out beyond the entl of the villus and join with those from the neighboring villi. The syncytiiun resembles the so-called primary syncytiunl. Maternal blood is found in the spaces between the fetal tissues. X 180.8.

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?
