Fig 14. Decidua

14 This photomicrograph of the decidua. Vera shows the enlarged and tortuous glands filled with secretion. The superficial venous sinuses are dilated. The spiral arteries extend to the surface of the vera. The superficial half of the Vera is edematous. Surrounding the spiral arteries the deeidual tissues are more dense. x 54.1.

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?
