Question

Match the number to the term that belongs in the text box with this description of the fetomaternal junction. A term can be used only once. "The fetal part of the placenta (1. chorion) is attached to the maternal part of the placenta (decidua 2. 0). by the 3.0 shell- the external layer of the trophoblastic cells on the maternal surface of the placenta. The chorionic 4.0 attach firmly to the decidua basalis through the cytotrophoblastic shell and anchor the chorionic 5.0 to the decidua basalis.... As the chorionic villi invade the decidua basalis, decidual tissue is eroded to enlarge the intervillous space. This erosion produces several wedge-shaped areas of decidua, placental 6.[1. that project toward the chorionic 7.-the part of the chorionic wall related to the placenta. The placental septa divide the fetal part of the placenta into irregular convex areas-8.0Expression of the 9.0. Gcm1 (glial cells missing-1) in trophoblast stem cells regulates the branching porcess of the stem villi to form the vascular network in the placenta... The decidua 10.0, the layer of decidua overlying the implanted chorionic sac, formas over the external surface of the the sac." A. septa B. capsularis C.plate bali F. transcription factor H. cytotrophoblastic I. cotyledons 10

Explanation / Answer

1) The fetal part of placenta is known as villous chorion( G)

2) The maternal part of placenta is known as decidua basalis (D)

3) The two portions are held together by anchoring villi (J) that are anchored to the decidua basalis by the cytotrophoblastic shell

4) The choronic villi are outgrowths of cytotrophoblast (H)

5) capsulans (B)

6) sac (E)

7) plate (C)

8) septa (A)

9) transcription factor (F)

10) cotyledons (I)
