I am a second year medical student. Embryology has always been tough for me because I couldn't imagine. We had studied about gastrulation in first year but my orientation was lacking. I came to this video after watching 3D tour of second week of development. I can't thank you enough. Now my orientation is clear. I could finally understand every bits and pieces. Thank you for this animation sir. Love from Nepal 🇳🇵
Great work sir, I hope this stays on internet forever & will make sure it reaches every medical student. Such a beautiful explanation. Made embryology easy!!
Never seen such amazing lectures on you tube. Don't know how to thank you. Skipped embryology in my first year but now watching you videos have made embryology easy for me.
We should thank you. U shouldn't thank us because u made it easy to understand and explained each and every question that I have..! Once again thank you🙏🙏🙏 bro 😘😘
Sir ur a life saver in mbbs first year ,i try to many platform like Marrow,prepladder but can't understand the concept, Thank u so much ,God bless u ,stay always happy ❤
Sir,this sequence of lectures,your way of explaining each nd every step is beyond the words "Thank You"...May Allah Almighty bless u with whatever you want(Amen).🤲🏼♥️
I too am so lucky to have such nice audience who regularly motivate me to work harder on this project. Thank you so very much for this uplifting comment. You are most welcome.
Sir I was facing alot of difficulties in this topic but after watching your video I understand everything and also all my doubts are clear now ,plzzz sir. Make videos of more chapters sir ,❤❤❤❤
I love the way you teach. You have a good sense of humour. As well you can make a complex topic very simple and easy to understand. Only good teachers can do this. Thank you for this class :-)
Thanks sir you aree doing great job.... thanks for explaining things so nicely.. earlier i was finding difficulty in understanding the embryology....in textbooks it is written in very confusing way... thankyou sir
I have questions is the primitive streak give information to create human body ?? Some people say primitive streak is responsible for creating human body (embryo) is that true ??
You presented and answered questions i didn't even think of! Amazing work! You earned a sub from me😄. Please keep up the AMAZING work! Love from Sri lanka 🇱🇰❤
Thank u so much for this explanation. I'm literally watching and clapping. However, I would like to know where the splanchnic mesoderm came from because I used to think it was so e of the cells from the ectoderm layer that formed it.
I sincerely apologize for the late reply. And thank you so much for your appreciation. The origin of extra-embryonic mesoderm (both splanchnopleuric and somatopleuric) is controversial. Most people believe that it arise from hypoblast cells. (specifically, yolk sac endoderm). While some say they arise from cytotrophoblast or from epiblast. There is some contribution from the epiblast as well. During gastrulation, some of the epiblast cells migrate laterally to contribute towards the extra-emrbyonic mesoderm. In summary, there is no definite answer to this question. But most common view is that they originate from "Yolk Sac Endoderm".

Sir i have a question when the epiblast in periphery migrate goward the center ofc the adhesive junction gonna be broken so the cell can migrate when they reach primitive streak thy gonna establish another junctions so we need we break it down so they can migration down through the groove ?
Information for whole of the human being is in every cell starting from zygote (in the form of DNA). Epiblast forms the complete human. The primitive streak "guides" the epiblast in forming the three germ layers. So in a sense we can say that primitive streak contains the info to create human being.

Are the first blood cells that form in the yolk sack coming from epiblast or hypoblast origin? As I understand it’s coming from hypoblast so it’s not completely true that the epiblast gives rise to all types of cells in the embryo because some blood cells formed by hypoblast right ? Or am I wrong ?
@@MedicoVisual Thank you very much for your answer doctor Do you mean the extra or the intra embryonic mesoderm ? And doesn’t that mean there are embryonic cells that doesn’t form by the epiblast ?
@@taashin2863 you are always welcome :-) Most of the blood cells are derived from the IntraEmbryonic mesoderm.. However some early blood cells are derived from the blood islands that form within the extraembryonic mesoderm. The origin of extraembryonic mesoderm is controversial. Most people believe that it arise from hypoblast cells. (specifically, yolk sac endoderm). While some say they arise from cytotrophoblast or from epiblast. So if the hypoblast origin of extraembryonic mesoderm is true, then yes, early blood cells are NOT epiblastic in origin. Great question though
There are two main type of embryonic cells: 1. Epithelial cells: that are structurally defined properly i.e. They have specific shape like Cuboidal, Columnar, Squamous etc. Furthermore, the epithelial cells are inter-connected with each other through cell-to-cell interactions. 2. Mesenchymal cells: On the other hand, are irregularly shaped and are not connected with each other. They are interspersed in a ground substance. The mesoderm is the major source of mesenchyme. That is why often in literature specially during teaching 3rd week, these terms are interchangeably used. But please note that mesenchyme can also arise from Neural Crest Cells. And sometimes by other layers.
Somany Muslims talked about this Islam miracle the primitive streak / but I just wanted to be sure that the primitive streak is involved of creating the human embryo 💙
prophet Muhammad he said: god created humans from (coccyx) tail bone / and science says this coccyx before it was (the caudal eminence) and this (caudal eminence) before it was (the primitive streak) 🧠🧠🧠
I was gonna tell you why this question so important to me but you asked anyway / I can prove my claim on Google if you want just ask me anytime / thank you again you really helped me ❤💚
At 05:52, there is a mistake. Hypoblast cells give important instructions to overlying *"Epiblast cells"* [Not Hypoblasts]
Good easily understandable presentation.it is very helpfull for first professional students

Sir i have a question when the epiblast in periphery migrate goward the center ofc the adhesive junction gonna be broken so the cell can migrate when they reach primitive streak thy gonna establish another junctions so we need we break it down so they can migration down through the groove ?
Yes, that's correct. Intercellular junctions are broken and the epithelial cells are converted to mesenchymal cells.
hello can i ask a question please? what is the name of the app or site that you use for these presentations
For 3D modeling and Animation; I use Blender. For 2D graphics and presentation; I use PowerPoint.
