- internal iliac artery | |||
|| Incorrect! internal iliac artery | |||
- uterine artery | |||
|| Incorrect! uterine artery form anterior division of the internal iliac artery, spiral arteries are invaded by trophoblast cells that remodel them into highly dilated vessels. See the [[:File:Uterine arterial vessel cartoon.jpg|image or uterine arterial vessels]] | |||
- arcuate arteries | |||
|| Incorrect! arcuate arteries, also called helicine arterioles are not remodelled, spiral arteries are invaded by trophoblast cells that remodel them into highly dilated vessels. See the [[:File:Uterine arterial vessel cartoon.jpg|image or uterine arterial vessels]] | |||
- helicine arterioles | |||
|| Incorrect! helicine arterioles, also called arcuate arteries are not remodelled, spiral arteries are invaded by trophoblast cells that remodel them into highly dilated vessels. See the [[:File:Uterine arterial vessel cartoon.jpg|image or uterine arterial vessels]] | |||
- radial arteries | |||

+ spiral arteries | |||
|| Correct! spiral arteries are invaded by trophoblast cells that remodel them into highly dilated vessels. See the [[:File:Uterine arterial vessel cartoon.jpg|image or uterine arterial vessels]] | |||
{Which of the following terms best describes the form of human placental organisation/classification? | |||
|type="()"} | |||
+ Haemochorial | |||
|| Correct! In human placenta where the chorion comes in direct contact with maternal blood. | |||
- Endotheliochorial | |||
|| Incorrect! Endotheliochorial placenta is when maternal endometrial blood vessels are bare to their endothelium and these comes in contact with the chorion ({{dog}}, {{cat}}). The human placenta is haemochorial where the chorion comes in direct contact with maternal blood. | |||
- Epitheliochorial | |||
|| Incorrect! Epitheliochorial placenta is when maternal epithelium of the uterus comes in contact with the chorion, considered as primitive ({{pig}}, {{cow}}). The human placenta is haemochorial where the chorion comes in direct contact with maternal blood. | |||
