cho·ri·on·ic plate

that portion of the chorionic wall in the region of its uterine attachment, which gives rise to chorionic villi; it consists of the mesoderm that lines the chorionic vesicle and, on the maternal side, of the trophoblast that lines the intervillous spaces; in the last half of gestation, the mesodermal connective tissue is largely replaced by fibrinoid material, and the amnionic membrane is adherent to the fetal side of the plate.

chorionic plate

Etymology: Gk, chorion + platys, flat
the part of the fetal placenta that gives rise to chorionic villi, which attach to the uterus during the early stage of formation of the placenta. It forms the fetal side of the placental disc, and its development is responsible for a normal placenta.
