Zusammenfassung

Das kontraktionsfreie Myometrium bietet zusammen mit den Eihäuten und der geschlossenen Zervix dem Fetus eine geschützte Umgebung für eine ungestörte Entwicklung. In dem Grenzbereich bestehend aus Dezidua und Zervix einerseits und der Plazenta mit den Eihäuten andererseits kommt es zu einem direkten Kontakt zwischen mütterlichen und fetalen Geweben. Der Schutz des hemiallogenetischen Embryos vor Abstoßungsreaktionen des mütterlichen Immunsystems sowie die Versorgung des Fetus, die durch die speziellen Gewebsstrukturen, die sich in dieser Kontaktzone in der Frühschwangerschaft entwickeln, gewährleistet wird, sind für die erfogreiche Schwangerschaft von zentraler Bedeutung. Dieser Bereich entwickelt ferner endokrine Funktionen, durch die die Anpassung des mütterlichen Organismus an die besonderen Bedürfnisse einer Schwangerschaft erst möglich wird.
