Many thanks to BNX for sponsoring this video. BNX makes high-quality American made N95 masks/respirators. I wore them instead of the usual N95 masks I am required to wear and found them considerably more comfortable than the hospital grade masks that provide the same protection. They are lightweight, comfortable, and lint-free.

SUMMARY OF THE VIDEO FOR YOUR NOTES
------------------------------------------------------------------------
Placenta development begins during implantation of the blastula. This blastula contains an inner and outer cell mass. The inner cell mass further is differentiated into the epiblast, which the 3 germ layers are derived from, and the hypoblast. The outer cell mass contains the trophoblast cells, and it is the trophoblast that forms the placenta
Once implantation begins by about day 6, the trophoblast cells interact invade the epithelium of the uterus. This invasion is deep, and by day 8 the trophoblast will differentiate into the syncytiotrophoblast and the cytotrophoblast.
Syncytiotrophoblast produces human chorionic gonadotropin hCG by week 2 and this is what is tested on pregnancy tests
By day 9 lacunae form within the syncytiotrophoblast. As the syncytiotrophoblast continues to invade and erode materal tissues, blood is now allowed to enter the lacunae from the spiral arteries, and thus the earliest fetal circulation is established by the end of week 2.
As this occurs the cytotrophoblast forms the primary chorionic villi which penetrate the syncytiotrophoblast again. Soon, extraembryonic mesoderm will grow into the primary chorionic vili to form secondary coronic vili, and they become tertiary villi when embryonic blood vessels form into the embryonic mesoderm.
The tertiary villi grow towards the decidua basalis which is the maternal component of the placenta and anchor into it. These anchoring villi further grow into the intervillous space to increase the surface area between maternal and foetal placenta to increase the amount of nutrient exchange. These villi are called branching vili, and this is exactly how you should imagine it. The branching villi spread around to increase the surface area for nutrient and metabolite absorption from the maternal circulation.
Cytotrophoblast cells invade maternal spiral arteries replacing the maternal endothelium, this is important as these cells are now larger in diameter thus reducing the resistance of blood flow to the foetus. When the cytotrophpoblast do not completely differentiate in this way, pre-eclampsia can occur which can have disastrous consequences for mother and baby.
The ductus arteriosus is important when treating some life threatening congenital heart defects. One example is when a baby is born with transposition of the great arteries. In this condition, the ascending aorta and the pulmonary trunk are switched, leading to an inability for oxygenated blood to leave the pulmonary circulation and enter the systemic circulation. Prostaglandin E2 is often administered to maintain the patency of the ductus arteriosus until a surgical correction can be made. This allows for blood to mix between the two distinct circulatory circuits.
There are three shunts in the blood circulation of a foetus. These are the ductus venosus, ductus arteriosus, and the foramen ovale.

Thankyou.
Doctor, My daughter is born without the thyroid tissue(agenesis). Can you please explain what may be the cause.
Hey, I'm sorry about your daughter, hopefully she is otherwise healthy and doing well. I believe thyroid agenesis is due to mutations in the genes responsible for thyroid development but the cause of this I believe is unknown. Important thing is not to blame yourself, it wouldn't have been anything caused by yourself or your partner. I wish you guys all the best, and the best health for your daughter.
Thank u for your efforts to make such a knowledgable content

Grateful boss❤
thanks Doctor, It's amazing how simply I got high score of understanding.
Very helpful 😊
Thank you very much for the big help with your textbook. I would like to know what happens with these cells from the second arch, that become overlapped and why is the tongue called a muscular hydroplast? Thank you for answering me.
So grateful for these videos, thank you so much!!
at what point are iris colobomas formed?
شرحٌ جميل، هداكم الله وجزاكم خيرًا.
wonderful videos. thank you sir
i love the quality of this video, what's the name the gear/camera used for the filming
It was a smartphone balanced in between some textbooks on a chair on a table
Emporio is very difficult to study, but you make it easy for me to study, thank you❤❤
Thank you for this excellent video! As a plastic surgery resident, I found your explanation of the embryology of the face and palate incredibly clear and informative. The detailed insights you provided are invaluable for my studies and future practice. Keep up the great work!
Thank you for the basic embryology illustration and amazing explanation
amazing video! keep it up man!
U deserve more than the best Thank you ☺️
Thanks for the video I thought I was cooked
HEY can you talk about the origin of the diaphragmatic crurae?

The best one teaching embryology
Thank you Dr. Minass
omg this channel is Gold
Well done video
Thank you so much😭 this is so easy to grasp🎉
In the circulation part for the embryo he mentioned the blood go through patent ductus arteriosus! It goes through ductus arteriosus Patent ductus arteriosus is a malformation which means after birth it will still be open it won’t close. Keep that in mind guys
Thank you!
Thankyou sir
that was amazing , thank you sir🙏
Hey Dr I have a question Is the ventral pancrea surounded by ventral mesogastrium and the dorsal pancrea by the dorsal mesogastrium. I'm a bit confused, Ty
