Lockdown Embryology with Prof Alice Roberts #5: Embryonic Folding

How do you start to make a 3D body - out of a flat disc? The answer lies in the folding that happens throughout weeks 3 and 4, when the trilaminar germ disc curls from head to toe and side to side and ends up looking like a cross between a sausage and a pea pod. Watch it happen!

who knew learning embryology could feel so therapeutic

[@johnbarnes6568]

Very few and far between that you find videos on KZbin that actually spark your interest, ah gone are the days when I used to look like an angry mushroom with teeth. Alice Roberts has one of the most soothing voices on the planet.

Feeling slightly stressed about my MRCOG exam *tomorrow* - these are so soothing and a great way to gently revise and actually appreciate how amazing we all are, regardless of the exam outcome! Many thanks.

Life was so easy when I was a trilaminar germ disc!

[@AyhamHowrd]

I was hating studying embryology but your passion literally brought a lot of nice feelings, even though I am still confused it feels like you are bringing me closer to understanding the orientation of development! Thank you

[@mcc.o.4835]

One of the best channels on KZbin. Love this. 🥰

[@aliceroberts4107]

Wow, thank you so much!

[@Amazing_Mark]

The artistic ability of Alice is extraordinary. 👌

[@Sunlight70]

A cup of tea and one of these videos and suddenly the world seems a better place. Thanks, Prof Alice - please, keep 'em coming!

[@sumedhajha7803]

Never imagined that academic videos could be so calming to watch..

[@harsh5544]

Was stuck with my notes of embryology, this is so much better and thoughtful 😍👏 Great work ma'am !!

[@MrNas42]

Wow! So beautiful. Beautifully illustrated and beautifully told ...

[@sarahlucas1999]

I love this series and your illustrations are amazing. Can't wait for the next one :)

[@markyhmarcus]

Fascinating, and the detailed illustrations you draw so reminiscent of Tony Hart of take Hart fame.

[@davidkennedy7178]

Alice, this is brilliant; the explanations and the accompanying artwork make it all so easy to follow. A question though. You say that the "heart" is now beating, but presumably at this stage it's not "pumping" anything but ticking in a vaguely similar way to peristalsis in the gut (very vaguely similar!)!

[@stephaniemaria9095]

Love this Alice, thank you so much for doing this! I'm week 16 so it's exciting to see the week to week in detail X

[@paulinesim9909]

These are amazing, studying for MRCOG part 1, and really hope that you can do up to week 8 before the 28 September! Thank you for finally allowing this to make sense to me

[@aliceroberts4107]

Pauline Sim Thank you so much! I’m away filming now but will try to get some more done towards the end of Sept - hopefully in time for you!

[@andyrussell916]

I'm disappointed there are so few views, as these drawings are exquisite! Please carry on with this fascinating subject. I have a question that I once heard in my Human Biology A-Level class back in the early 1980's is that "Embryology recapitulates phylogeny" is this statement true given that all animals that follow a common ancestry must follow a common development path...?

[@musicaljoy]

Really enjoying these videos

[@nml1930]

Thank you so much!

[@sajjadkhan9710]

what a excellent work, very interesting love it. Thanks professor

[@phonotical]

I am growing attached to this fictional embryo... aint life weird haha

[@Monpjc]

Thank you for another amazing video Alice, I was very intrested to hear the heart was starting to beat at just 26days, Would this imply that the Nural Nodes have formed and are regulating the heart already, it so then I assume nurons in the brain have started to form also? Still find it amazing that with so much growth that there is not any trace of a bllod supply coming from the mother? Cant wait for next video -!

[@tobiasrankin9606]

Professor Roberts, please can you tell me what paper you use to do your beautiful composition on?

[@calinperse2996]

Alice, how did you proceed with the front footage?

[@pjw1016]

I find it interesting that the ancient Egyptians believed the soul entered the body around day 49, that I believe coincides with the sexual differentiation of the embryo.

[@mustafabozoglan]

👏 👏 👏 ❤️❤️❤️

[@colsylvester639]

How does the connecting stalk migrate from above the epiblast to parallel to it?

[@aliceroberts4107]

Col Sylvester Not sure - I’ll look into it - but let me know if you discover an answer!

[@colsylvester639]

@@aliceroberts4107 It looks like the stalk migrates around the amnion. embryology.med.unsw.edu.au/embryology/index.php/Paper_-_The_Formation_of_the_Connecting_Stalk_and_the_Extension_of_the_Amniotic_Cavity_towards_the_Tissue_of_the_Connecting_Stalk_in_Young_Human_Embryos
