BGDA Practical - Placenta and Fetal Membranes
Practical 3 - Fertilization to Implantation | Practical 6 - Implantation to 8 Weeks | Practical 12 - Fetal Period |
Introduction
From implantation through the remainder of prenatal development the parts of the conceptus that did not contribute to the embryo now develop and differentiate in parallel to form the embryonic placenta and the fetal membranes. Remember that the placenta has a dual origin from both fetal and maternal contributions.
Clinically, the placenta is first observed by ultrasound and both the site of formation and its development are critical to fetal development. The placenta and the fluid within the fetal membranes, are an important diagnostic tool for the genetic status of the fetus. At birth, in recent years, the cells derived from the placental cord are now an important source of “cord stem cells”. These will eventually have many clinical therapeutic applications.
Aim
To understand the development, anatomy and histology of the placenta and the fetal membranes.
Practical 14: Implantation and Early Placentation | Villi Development | Maternal Decidua | Cord Development | Placental Functions | Diagnostic Techniques | Abnormalities |
Key Concepts
Implantation, uterine changes (endometrium to decidua), early placentation (cytotrophoblast and syncitiotrophoblast cells), villi development, placental cord, placental function, placental membranes, abnormalities.
