i'm not too good on youtube so instead of sending a message i'll just write here: i'm from Buenos Aires, in 2nd year of medschool and your videos are what i've been looking for on youtube for months. really. i don't understand why you don't pop up first on searches because your videos have been the most helpful, by far, i've seen. you explain things very clearly with the perfect amount of depth. thank you for everything you do, your videos and existing :) appreciate it loads.

Man, you are an amazing teacher - finally i get to understand embryology. English isn't even my mothertongue and you speak quite fast, but how you structure your lesson is way better to understand than any lecture I heard or script and book I got to read in my german university so far. Thank you so much!

Thanks for the great lectures! They include plenty of information without too much fluff, and they're very easy to follow!!

You are the reason I passed my anatomy class!!! Love your lectures!!

Your videos save this med student every time. Thank you and keep it up!

Amazing videos! Thank you sooo much!!! First year of medical school in Switzerland, and this is sooo helpful. Keep up with the fantastic work! Have forwarded this chapter of videos to my fellow students

Finally a way to understand embryology, medical student from Sri Lanka, you’re really saving the day, thanks a lot!

This guy is very good. I will subscribe God bless u man u are saving lives here and goodluck to the AK lectures..

I'm from Russia, hi! Your videos are the most informative i've ever seen, thank you!

Thanks you for the hard work and amazing lectures, i just wanted to note that the Morula is a 16 cell structure not 32

Your lectures are always amazing!!! Thank you!!!

Sir just found this video and this was like the best video for the topic... Excellent explanation... Thank you sir!!

So one question I have is. What problems would an animal made of a solid spherical ball of cells experience? My answer is that cells inside of the spherical ball would have a hard time receiving nutrients from the surrounding fluid, excrete waste, and exchange gases. and blastulation fixes this problem by increases the surface area to volume ratio as well as exposing cells to outside fluid.

Hello, I am also a medical student and these videos are amazing. You explain things very well and to the perfect level of detail. However, may I suggest that you either number your videos or tell viewers what video to watch next after the one they have just watched so they can follow the process. Ex: can you put all of the steps of the embryonic develop into order? Other than that, these are fantastic! Great job :)

thank you so much sir! you explain so well. it helped a lot. :)

This is absolutely amazing !,you are an incredible teacher!❤

You really teaching well, I enjoyed it. I am a first year student of dental University and I study English but it is not my mother tongue. You explained so well that I taught it to my friend. If there is a heaven, it will be for your.❤🎉

Great lectures Andrey, please upload more content :)

I suggest that you take a picture of the board and download it to those who want to study which ones are better than capturing the screen🤷🏻‍♀️

You do an amazing job. Cannot stress that enough.

You are world class teacher, thanks for the great job...God bless

Thank you sooooo much!

you save my time :) thanks a lot!

If the first mitosis division doesn't happen until 30 hours after fertilization and the next few mitotic divisions take their time as well, how do you refer to that as "very rapid" mitotic divisions.

This is amazing! Can you please make a video on patterns of cleavage?:)

I'll always pray for your best coz u deserve it..from Kashmir

awesome teaching

Is there a video explaining the types of cleavage depending on the amount of yolk?

When the zygote divides into the morula, will the mass of genetic information inside each blastomere be the same?

Subscribed!!! Dude is the shit!!

5:22 if anyone wants screenshots 🙋🏻‍♀️

isnt there a difference between mitosis and cleavage? The nucleus doesn't divide in cleavage.

Hi. This is very helpful.😍 Can I ask these question? 😊What would happen if one cell was removed or damaged at the 2 cell, 4 cells, and 8 cell stages?And What would happen if the two cells were separated after the first cleavage and allowed to develop on their own? I hope to get a response from you. 😊 Thank youuu.😊

Isn't the definition of a morula a 16-cell shape?

Just amazing ❤️

Respected Sir, Your video is quite informative ....I have one question" how much time 2-cell embryo takes to become 4-cell"...Thanking in anticipation...

Morula has 16 cells not 32 as it is mentioned in the video at 5:11.

Thank you sir

Excellent videos! Who styles your her?! Lol...

How are these Celled kept toghether? and not forming another individual

I thought the Morula was the 16-cell stage?

GOAT!

sir,could you explain planes of cleavages

I'm low key encouraging my friends to become pregnant so I can explain to them exactly what's happening in their uterus. XD

Like, subscribe, and comment a thank you so people will be more likely to find your videos.

isnt morula 16 celled

pretty sure a morula is 16 cells, not 32

He sounds like the bat from Anastasia. Lol.

Isnt morula 16 celled? Pls answer fast

My dam wish is to meet you sir.

Morulla contains 16 cells or 32?!

Wow Sir 👌👌👌👌👌👌❤❤❤❤❤❤❤❤❤❤❤❤

Am I the only person watching this for a level biology?
