This man single handedly saved me when we started embryology last year and I'm back this year as we go into organ formations. My absolute fave for this kinda content. Hope he's having a good day
Hi sir I'm from India, cannot but to write for the video, Bcz these are so impressive .
Now I'm in high school and aspiring medical student.
3 things that hypnotized me is 1) detailed description of mechanism of formation
2) scientific logic , while you explained why there are so many cavities
3)Most impressive and unique way of explaining why they named so . It is a great way to understand things which makes us free from cramming and makes interesting . Reason for naming every structure is absolutely a rare idea which is introduced by u ONLY and ONLY.
And thereby your aim to create this channel "understand medicine" is damn justified .(as you mentioned and as I read every bit of this channel with utmost sincerity) .
But sir my request with earnest exhortion is , as u know how vast the medical science is ,therefore you make the "entire course" of medical sciences available .A large number of students around the world who are preparing for usmle like exam will be ready to pay for it, Bcz your videos are far superior than other famous platforms where students pay for. Plz sir consider my request,as you could perceive my love and respect for your content.plz consider sir. Students needs you .i really mean every word i have been writing. Plz sir , consider my request .
Sir I'm from India . I'm a 1st prof MBBS student . Your explanation is very easy to understand and it gives me a crystal clear concept . Through the whole year I can't understand properly the topic as I can't visualise the changes. Your Vedio lecture is really nice to visualise the whole topic .Thank you so much sir💖💖💖. May Allah bless you 🤍🤍🤍..A lot of love from India 💖💖💖
I am so glad that my lectrues helped you. Thanks a lot for your love and support. Most of my students are from India. Love from Pakistan ❤️
Ample of thanks and love from Pakistan...I have no words to explain how u helped us ...
Expecting da u will keep it up ... inshallah in d second yr I will start ur special ( systemic) embryology from the very beginning of yr...
Stunning, stunning, Dr Aizaz!! Your precise and detailed explaining in defining words, why things are named what they are named, along with your emotional inflections of voice all show us your detailed involvement and enjoyment you have as you present to us this wonderful period when we were in our mother's womb, not knowing that one day we will learn where we once were!!! Each lecture is getting more riveting as you make it so excellent!!! My jaw keeps dropping in each video, 1) at the unimaginable complexity at what is going on, and 2) your gripping explanation of this staggering complexity in so short length of video. I can only imagine the many more fabulous videos still in this playlist!! Thank you and your team for all this fabulous effort.
He is so underrated I can’t😭😭
Sir 1st lot of respect from India 🇮🇳🇮🇳. Ur way of teaching is awesome and sense of humour is great 😂😂
Very well elaborated lecture on developing embryo during second week of embryonic life. This is very informative and helpful for medical students as well as other medical professionals. Exellent work
Thank you so much
Your knowledge about the topic is commendable
Hello from Romania! Excellent video! I learned so much from you! Keep posting. I am waiting for your next video!:)
Awesome! Thank you!
Now I believe that I don't have to prepare my embryology lecture for my students from any book just watch your video and its done, Amazing job Dr Azaz I am huge fan and I am trying my best to spread a word about this treasure among my students and you will get your due credit what you really deserve. Keep working hard, you will be recognised by every medical student around the globe one day,
And believe me you have taught me one thing more that one can learn from anyone it is not necessary to be you seniors you look upto but sometimes they might be your juniors who aspires you. Keep doing hard work
Inshallah
Thank you so much sir. I am blessed and honoured to have someone like you in my audience. God Bless you sir. You are truly a great inspiration and motivation for me.

(We created the human from an essence of clay: (12) Then We made him, a drop, in a secure receptacle (the womb) Then We created of the drop, a clot (of congealed blood) and We created the clot into bitesize tissue, then We created the bitesize tissue into bones, then We clothed the bones with flesh, and then produced it an other creation. Blessed is Allah, the Best of creators! (14) Quran . Sura 23: AL-MUMENOON (THE BELIEVERS) - verse 12--14
Plz also make video on EMBRYONIC AND FOETAL PERIOD
Sir can you share 3d animation of syncytiotrophoblast how surrounds the whole embryo
I'm just confused I looked into several books ( langmans...) they mention the development of amniotic cavity first then the exocelomic pls correct me if I'm wrong
Both are developing side-by-side (almost at the same time). Its just that logically I found it easier to describe the development of trophoblastic part first.
Great lecture thank u so much I just have a question when the syncytiotrophoblast erode the blood vessels how can the arterial blood doesn't get mixed with Venus in the same lacunae?
Although the syncytiotrophoblast does erode into the walls of maternal blood vessels, the arterial and venous blood do not mix within the same lacunae due to the unique structure and organization of the placenta's vascular system.
The maternal blood enters the intervillous space through spiral arteries, which branch out and supply blood to different regions of the placenta. The blood then flows around the chorionic villi (fetal blood vessels covered by the syncytiotrophoblast) and exchanges nutrients and gases with the fetal blood. After the exchange, the maternal blood collects into venous channels and leaves the intervillous space through the endometrial veins.
Several factors prevent the mixing of arterial and venous blood in the same lacunae:
1. Gradient pressure: The pressure gradient between the incoming arterial blood and outgoing venous blood in the intervillous space helps maintain the unidirectional flow and prevents mixing.
2. Continuous flow: The maternal blood flow in the intervillous space is continuous and unidirectional. This flow pattern helps maintain the separation of arterial and venous blood within the lacunae.

@@MedicoVisual thx a lot
Sir please tell me if trophoblast is divided into synctiotrophoblast and cytotrophoblast are formed in second week or in the first week! Book mei it’s mentioned in the first week and you said at the end of the first week! So is it the last event of first week or first event of the 2nd week! I am so confused and I have a test tommorow please answer
Division of Trophoblast typically occurs on 6th or 7th day (end of 1st week). However, it is possible that it may be delayed by 1 to 2 days.
It is less likely that trophoblast's division is postponed to 2nd week. Because syncytiotrophoblasts are crucial for implantation that occurs at the end of 1st week of development.
Thankyou sir!!!!❤️
Sir, thank you soo much for this exceptional video. Sir, a question. Are the cells of the epiblast stratified columnar while the cells of the hypoblast simple cuboidal ??
Both are non-stratidied. Epibast is simple columnar while hypoblast is simple cuboidal.
Understood sir, thank you
❤️❤️❤️❤️💯💯💯
Very I need to join in his lecture how I can do that
