{The maternal endometrium response to trophoblast invasion is called the decidual reaction. | |||
|type="()"} | |||
+ true | |||
- false | |||
|| Yes, the endometrium becomes decisualised, deposits fibrinoid and also forms epithelial plaques. | |||
{The human placenta is classified as : | |||
|type="()"} | |||
- Endotheliochorial | |||
+ Haemochorial | |||
- Epitheliochoria | |||
- Mesoeliochorial | |||
||Haemochorial - placenta where the chorion comes in direct contact with maternal blood (human) | |||
{Stem villi - or terminal villi, are the region of main exchange, surrounded by maternal blood in intervillous spaces. | |||
|type="()"} | |||
- true | |||
+ false | |||
|| Stem villi - or anchoring villi, cytotrophoblast cells attached to maternal tissue. | |||
{The 4 cellular layers separating maternal and fetal blood in sequence are: | |||
|type="()"} | |||
- spiral artery wall, Nichbaur layer, cytotrophoblast and Hofbaur layer | |||
+ syncitiotrophoblast, cytotrophoblast, villi connective tissue and fetal capillary endothelium | |||
- maternal lacuna, trophoblast layer, endothelial and fetal red blood cell | |||
- fetal capillary endothelium, villi connective tissue, cytotrophoblast and syncitiotrophoblast | |||
||Maternal and fetal blood normally do not mix and all exchange occurs across these cellular layers. Later in development the syncitiotrophoblast layer may not be continuous on the villi surface. | |||
