If the blastopore was an anus, then where is the origin place that mouth has developed? is it ventral lips or at another end of the archenteron? (sorry for my bad English)
Biologists shouldn't even be allowed the job of naming things IMO. The naming NEEDS to be done by physicists because it has really gotten out of hand...
what is hard in the names? it actually has a meaning, ectoderm = ecto + derm (ecto = εκτος (greek word for outside)) derm = δερμα (derma) greek for skin/tissue, meso = middle, endo = inside
it's well made bro, thank you a lot for this animated video. It helps a lot understanding the phenomenon
It's been so many years. Still the best video on RUclips ever.
Best Video On RUclips.
Well Explained.
Short and Easy To Understand.
Best video ever
I understand in few minutes what i didn't understand it in 1 hour thank you⭐⭐
Thank You Nancy.
People Like You Made My Day ☀️
GOATED thank you so much for this video!
Thank you, perfect and simple explanation!
Very Good Explanation ❤
Thank you for the video!!!
I finally understood!
An awesome explanation of gastrulation ❤❤❤❤thank u sooo soo much it was really very helpful ❤❤❤❤#Love from Pakistan 🇵🇰🇵🇰
Thanks to you for watching and commenting on this video. ❤️
Keep uploading more!
So fruitful..
Love from nepal🇳🇵💗
I'll After My Exams. Studying Right Now.
Muchas gracias ❤ Está muy bien a animado y explicado el proceso. Mi profe me pasó a mi y a mis compañeros varios links para nuestras exposiciones.
Gracias por ver a Lady Random 🥰
Extremely well explained! Kudos
Hi, I come from Thailand! this video makes me understand the lesson. Thank you!
ขอบคุณมาก. คนอย่างคุณทำให้วันของฉัน 💥
찐이다.... 감사합니다 이해가 아주 잘 됐어요ㅎㅎ

If we looked at the cross section of embryo of fray, a ball of cell with fluid filled carly. Lan See pasto coel, and emriyo is in blastula stage of development.
Blastula contain large yolk filled cells at vegetal pole and small cell on animal pole
At the begining of gastrulation a few surface cells called bottle
cells, move into the embryo, followed by anterior of the other surface cells..
We can track the movement of cells into the embryo, It we have died a few surface cells.

At same time ectoderm extends around the embryo Surface in a process called epiboly. As the gastrulation proceed a cavity called the archenteron formed, and blastocoel Progressively shrinks.
Archenteron is primitive gut and
surrounded by endodermal tissue The
Cavity continues with the outside. where the blastopore, which eventually become the annus of the animal. As the endoderm extend around the embryo, another set of bottle cells formed - These calls migrate to the embryo, another surface cells

sr if u ll make futher little more about frog complete development.very understood
Nice video
Shukriya ❤️
😍It's a nice vedio. Easily understandable. Thank you 😘
Happy Learning ❤️
Thanks sir for the video and notes 📝
Thisis great! Thanks
🤗
Thank you !🙏🏼
😊
Thanks
Thanks!
Thanks for watching 👆
Verry nice..
Wooow thanks
short but useful 👍
Understood
At which of these cell stage of frog blastula a blastocoel is formed?
Everything is Explained in Description 😅
I came here looking for an Amphibia map
and then you find something Beautiful 😍
Bro, amazing video.. made me understand within no time...
what's the source of this video?
It's a Paid Content. Providing You Guys for free.
How can i get it if i want it by paying??

Thankss
Cô ơi em xem rồi nha ạ!
Can You Please translate this comment to English.
Thank You.
@@PhDWallahGamer Dear teacher! I saw this video! Thanks you!
Also Write this video down with your hands if u want to learn this concept for lifetime.
Thank You.
What is the secondly-made space under the ventral lip? is it aslo protogastor? I thought there’s only one protogastor in the embryo
Mesoderms come from micro or macromere ?!
Looks like micromers
From macromeres
The mesoderm comes from the marginal zone of the blastula.
Plz explain in hindi
Soon Mam.... Right now I'm busy. #exams
I'll be Uploading Videos in Hinglish Language... So Stay Tuned.
#HappyLearning
Do you need hindi translation of this video notes ??
If the blastopore was an anus, then where is the origin place that mouth has developed? is it ventral lips or at another end of the archenteron? (sorry for my bad English)
Read Description Please and Then watch video again.
Who's is here from St Mary's College ❤

thats what im saying
what is hard in the names? it actually has a meaning, ectoderm = ecto + derm (ecto = εκτος (greek word for outside)) derm = δερμα (derma) greek for skin/tissue, meso = middle, endo = inside
how so?
Yeah and doctors shouldn't be allowed to operate on humans, astronomers should do that.

Thanks
thank you!
