Medical Embryology - Development of Body cavities, Intraembryonic coelom, and diaphragm

Hi all, this short video covers a complex 4-dimensional topic, how the body cavities (pericardial, pleural, and peritoneal) develop and separate from each other. Derangement of this process can lead to congenital diaphragmatic hernias.
If you don't have a grip on early development (single-celled zygote up to the trilaminar stage), feel free to check out this video to get up to speed:

I hope you find this helpful!

Dr. Ward this was insanely good. Honestly, I couldn't make any sense of folding and spaces even after watching countless videos but yours just made perfect sense. Thank you very much!

[@pvcdoc2327]

The concept of the body cavities is brillaintly explained. There is no other video I've seen which explains this. I think the clue to understanding is to visualise the hollow U tube running around the embryo from one side around the cranial end to the other side and how the tube gets devided up. This is the most difficult concept in the whole of embryology to understand and visualise. Also how the lateral plates of the mesoderm split with what will "become" the "intraembryonic coelom cavities. They plit apart completely - one covers the gut tube and the other curls from both sides to enclose at the anterior aspect the body cavities to form the tube ! More compicated than the meso and paramesonephric ducts and the gonads !

[@syrianrami1]

I'm so late but I can't seem to understand how the two ends of the U make the peritoneal cavity. Wouldn't that mean we would have two peritoneal cavities??? Or do the open ends connect due to lateral folding?

[@ashfly77]

You have a great gift for teaching! Thank you!

[@dzidzornucharles4584]

this video has just saved me from believing i cannot understand the concept of cavity formation. thank you

[@health-horizon-one]

finally what had been confusing to me is solved.Thanks alot GOD bless you

[@DrP3natrator]

WOW, excellent video. I was struggling with those body cavity lectures, but this helped me put a moving picture to all those slides. Thank you!!

[@HongThaiHonzaLe]

I like how you pictured the formation of intraembryonic cavites gradually, in some textbooks it is shown like the cavity would had formed from the amniotic space

[@princygupta3186]

Dr. Ward , I'm a medical student from India and your videos have been immensely helpful in understanding various concepts of anatomy especially embryology ones. I have a little request, could you please do a video on peritoneum, it's attachments , the vertical and horizontal tracings ... I'm having a real hard time in trying to understand it and unable to get it from any book or some other video

[@prettyrocker4514]

also embryology of gut!

I realize it is kinda randomly asking but does anyone know a good site to watch newly released series online ?

what about the peritoneal space? where is it in the end? i heard about the pericardeal and pleural , but where is the peritoneal located? by the way you are an extraordinarily talented human being, thats something that 100% of the medical field mUST accept

[@kanishkagarg1391]

Please someone explain me the hollow tube that sir explained in video

[@samsaon7153]

How come we have a continuous pericardioperitoneal canal, if the heart developed above the stomodeum which is a fusion of ecto and endo indicating no mesoderm to form a tube?

[@dr.stethilo6093]

It Helped..🙂

[@aliceroxcullen98]

Dr. ward is there anyway you can make you drawings downloadable? Like a pdf or something. That would be very helpful as the diagrams given in my book are not detailed enough.

Does the pericardioperitoneal canal become the pleural space?

[@AbigailAda]

Hello Sir. Thank you these amazing videos. Please i really need your help. Can you refer me to any textbook or website which will tell me the actual organs which form in weeks 5 , 6, 7, and 8 of embryonic life? I have spent days trying to find information but I cant. I am supposed to do a presentation on the congenital anomalies which occur in weeks 5-8 of embryonic life. I know that organogenesis occurs during this period, however I want specific information of what happens in each if these weeks. The embryology behind the formation of these organs. I would really appreciate your help Sir. I hope to hear from you soon.

This is a great video but diaphragmatic hernias are typically repaired after delivery - and there are degrees of severity.

[@vishusingh6913]

11:44 sir, is it pericardioperitoneal canal or pericaridopleural canal???

[@beny4everinlove]

Dr. Ward, I'm a medical student from Portugal and if it wasn't for you, I would never have really understand embryology! I have just a little question related to this video, at minute 1:26, what is that red spot under intermediate and paraxial mesoderme that, for what i catch, will create the aorta? Thank you so much, Hope to get an answer from you.

[@chrishooper5851]

You probably figured it out by now, but the red spots are the dorsal aorta, going down each side of the body.

[@EVARyMM]

Umm...I have a question. Why does the hernia usually located on the left side?

[@ClinicalAnatomyExplained]

The liver is on the right and it takes up so much space that a diaphragmatic defect needs to be huge in order to pass through that side.

[@remusomega]

6:07 - I think this is incorrectly drawn. The endoderm is shown adhered directly to the ectoderm caudal to the oropharyngeal membrane. There should be a layer of mesoderm between this.

[@apurupamargapuri4192]

@@ravenmcmillin9533 they mean caudal to the oropharyngeal membrane. Not within the membrane itself
