chorionic plate
The fetal surface of the placenta where umbilical vessels branch and chorionic villi attach.
Full Definition
The chorionic plate forms the smooth, shiny fetal surface of the placenta, covered by the amnion and containing the major branches of the umbilical vessels. It serves as the foundation from which chorionic villi extend into the maternal blood space. Abnormalities of the chorionic plate, such as circumvallate or circummarginate insertion, can affect placental function and pregnancy outcomes. Proper identification is crucial during placental examination and fetal medicine assessments.
Usage
Usage note: Not to be confused with the maternal basal plate; always specify 'fetal surface' when clarity is needed.
