2h of lecture in 3min Tanx

I couldnt understand gastrulation just by reading about it, this cleared all my doubts. :)

Fr this video is incredible. Throughout 5h of embryology lectures, the two videos shown from this channel were the only things I truly understood two years ago. Now I‘m studying for an exam and this video is still gold.

Thank you for this video!!! So much clearer than reading from a textbook

It is seriously so helpfull to see this in video rather than reading a text. Very clear too, understood everything even though English is not my first language. Thanks!

Incredible video. Thank you so much. Perfect for refreshening my knowledge without painfully collecting information from textbooks for 2 hours

Perfect: the only possible word for this video. Loved it! Thanks a lot

I was so confused about cranial and caudal ends. The way you rotated it and showed it, now I understand what those images in the books taken from different angles mean.

Thank you soo much!helped me a lot!

Beautiful! Thank You very much

So much thanks for this video, it helps a lot.

Thank you so much, great video!

thank you so much for such a helpful video !!!!!

One of the best ways to demonstrate.

thank you🌼

Thank you veryy much!!!! Helped me a lot for my exam!.....

Thanks sir for your help😊

Thank you so much this was very clear

amazing video...thanks

also very helpful for vet med students :)

THANK YOU SO MUCH

Thank you so much. Now I only have to translate the technical terms, but without this I think I would have never understood.

Thanks the video is amazing

Thank you so much sir

Its reallly helpful.Animations helps aloot.......

thank u so much....so helpful

You are the best ❤️

im a first year medical student and this is so helpful!! thank you

thnkyou it help me a lot

Thank you very much.

Thank you so much

Thank you So much

really helpful

Thank u sir it is really very helpful 👍😁

Thanks. ❤️

nice video... it so helpful

thank you

thank youuuuuuuuu soooooooooo much!

MILLION TIMES BETTER THAN A TEXTBOOK

Thank u so much ☺️

Awesome

very helpful

Thank u!!!!

Thank you❤️🌸

amazing 10/10

Thanx alot

please tell about the mechanism of cell polarization during gastrulation

Thanks

So the endoderm proper is formed from the proliferating primitive groove cells and the ectoderm proper from the epiblast?

TYSM

Thnx man

THE LEFT & RIGHT SIDES ARE LABELED WRONG!!! It really confused us in our embryology class. I didn't want everyone else confused too.

No they're correct, I think. It's based off the embryo's right and left, not the viewer's.

Is there any video for neurulation???

Can i know, what kind of that gastrulation?

Tnx sir

does the primitive streak form in the amniotic cavity? i'm confused

@salsabilalbadan3

It forms in a part of the surface lining the amniotic cavity (epiblast)

better than my medical school lecture

Thank god

I have a question. Since the primitive streak is formed at the dorsal side of the embryo, shouldn't left and right be switched?

@Taylor-kj1mu

Imagine a fully grown person lying on their back on a table. If you were standing at the foot of the table, looking up at their feet, their right side would be to your left and their left side would be to your right. This is convention used in the video, and it's pretty much the standard for cross sectional views in the horizontal plane.

@estherywema6051

I think you're wrong there. The blastocoel is indicates the ventral side of the embryo, and the person is thus lying on their ventral side. We're indeed standing at the foot of the table, and thus is the right side on your right and the left side on your left. Or am just mixing up everything? ;)

@Taylor-kj1mu

You know what? I think you're absolutely right. I hadn't considered the fact that the neural plate forms on the dorsal aspect. I apologize for leading you astray! I guess the video is incorrect as well?

Primitive streak arrived at cranial end or caudal end?

I REALLY found it so difficult to understand it especially this lesson in biology (Embryologie) so how can I understand it easily ...if someone knows please share with me the information

Al final de la segunda semana de desarrollo, se formó el disco embrionario bilaminar que consiste en hipoblasto y epiblasto. A lo largo de la tercera semana de desarrollo, este disco bilaminar se diferencia para establecer tres capas germinales primarias. (proceso conocido como gastrulación). Alrededor de los 15 días después de la fertilización, se forma una estructura engrosada a lo largo de la línea media en el epiblasto cerca del extremo caudal del disco embrionario bilaminar. Esto se llama la línea primitiva. En esta etapa, la línea primitiva de la formación define los ejes principales del cuerpo del embrión, incluidos los extremos craneales (hacia cabeza) y los extremos caudales (hacia la cola), así como los lados izquierdo y derecho del embrión. en el extremo craneal del disco embrionario, la línea primitiva se expande para crear un nodo primitivo, que contiene una depresión circular, conocida como fosa primitiva. esta depresión continúa a lo largo de la línea media del epiblasto, hacia el extremo caudal del linea formando un surco primitivo. Una vez formadas, las células del epiblasto migran hacia el interior hacia la línea, se desprenden del epiblasto y se deslizan debajo de él, hacia el interior del embrión. Este proceso se conoce como invaginación. estas primeras células para invaginar a través del surco primitivo invaden el hipoblasto, y desplazan a las células. las células hipoblastas finalmente se reemplazan completamente por una nueva capa de células proximales, que se conoce como el endodermo definitivo. Para el día 16, la mayoría de los hipoblastos han sido reemplazados. Las células restantes del epiblasto ahora se denominan ectodermo y forman la capa más externa y distal. algunas de las células epiblastas invaginadas permanecen en el espacio entre el ectodermo y el endodermo definitivo recién formado. estas células forman una capa germinal, conocida como el mesodermo. Una vez se formó el endodermo definitivo y el mesodermo. Una vez que se completa la formación del endodermo definitivo y el mesodermo, las células epiblastas ya no migran hacia la línea primitiva. A lo largo de la gastrulación, el ectodermo continúa formándose desde el cráneo hasta el extremo caudal del embrión, estableciendo tres capas germinales primarias distintas en todo el disco embrionario. El proceso de gastruación es finalmente completo.

This is beautiful. My story looks like Anshika's

shit, i get it now. tysm!!!

Which germ layer forms first and which one is the last to form out of the three?

@rajeevreddy3315

Endoderm

At the end of the gastrulation germ layer formed is??

Sir What about Involution, Ingression Delamination and Epiboly

Good yr

at the beginning you talk about primitive streak forming in caudal end and then you talk about this end as a cranial part of a body... why?

@primalpictures-anatomyTV

3 жыл бұрын

Thanks for reaching out, Kristian. In the video we’ve said that the primitive streak forms at the caudal end of the embryonic disc. Then the cranial end of the primitive streak expands to form the primitive node. The head of the embryo will form at the extremity of the embryonic disk near the primitive pit, which is surrounded by the primitive node. We hope this answers your question. If you'd like to learn more, please email us at info@primalpictures.org.

is there still an archenteron for this organism?

@primalpictures-anatomyTV

2 жыл бұрын

Thank you for your query. The archenteron is a cavity surrounded by the endoderm, which later becomes the cavity of the digestive tract. As this video explains the gastrulation process of a human embryo, the archenteron would be present. Hope this answers your question.

My test is tomorrow so probably won't get a response in time but, don't the cells move by ingression, not invagination?

@primalpictures-anatomyTV

2 жыл бұрын

Thank you for reaching out. Our anatomy team has looked into this issue. The epiblast cells migrate inwards and detach from epiblast, then slip beneath into the interior embryo to form the definitive endoderm, hence the process should be referred as ingression rather than invagination indeed. We hope this answers your question and thank you for spotting the error. Our team is currently working to resolve it, and we will provide a link to an updated movie as soon as possible.

Does anyone else notice the buzzing sound in the background? It's bugging me.

Easy to understand as drinking water

Sir yeh kahan sey parha rahy means konsi books follow ki hui??

it it gastrulation in birds?????

Where is Hensen's node

plzzzz tell anyone

It is incase of human

Hi there, thanks for watching and your comment! Our anatomy team is aware of the left and right labelling issue at 1:06 - the labels should indeed be the other way around. Thank you to anyone who provided feedback on this error. Our team is currently working to resolve it, and we will provide a link to an updated movie as soon as possible.
