Fig. 23. Endometrial gland

23 Surrounding this portion of an endometrial gland in the penetration zone there is a syncytial cell mass. This mass has af brush border. The endometrial gland cells are markedly degenerated and in places entirely wanting. The gland lumen contains blood. X 395.

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?
