Embryology of the GIT I - Foregut (Easy to Understand)

The development of the foregut explained very simply!
In this video (part one) we will discuss foregut embryology.
If you are completely new to embryology and you want to understand it quickly, this should be the first video you watch:
- • Introduction to Embryo...
Post any questions you have about the video below, I read all the comments:

Summary for your notes:
- initially, the oesophagus is short, but as the heart and lungs descend, it becomes longer very quickly.
- the muscular coat formed by splanchnic mesenchyme is striated; the lower third is smooth muscle
- the stomach is a fusiform dilatation of the foregut at week 4
- the stomach is like Nikki Minaj, it turns to the side and grows posteriorly to show the greater curvature
- the posterior wall of the stomach grows much faster than the anterior wall
- that is, there is a 90 degree turn to the right, and there is anterior-posterior rotation (sitting on a hammock)
- the rapid growth of the posterior wall of the stomach forms the greater and lesser curvatures of the stomach.
- the rotation of the stomach along the longitudinal axis pulls the dorsal mesogastrium with it, which forms an omental bursa also known as the lesser peritoneal sac.
- falciform ligament and the lesser omentum are formed from the ventral mesogastrium
- the lesser omentum contains the portal triad (hepatic artery, hepatic duct, portal vein)
- free margin of the lesser omentum forms the epiploic foramen of winslow (the opening connecting the lesser to the greater sac)
- as stomach rotates, the duodenum takes on the form of a loop in the shape of a C and rotates to the right.
- the head of the pancreas and the proximal duodenum are now retroperitoneal organs.
Congenital abnormalities:
- Oesophageal atresia: abnormalities in partitioning of the oesophagus and trachea. Fistulas may also persist
- The proximal blind ended oesophagus, and a tracheoesophageal fistula to the distal part of the oesophagus is the most common type (90%).
- There are two other types which are much rarer (1% each). They include: (1) a proximal fistula, and a distal blind-ended oesophagus, and (2) a fistula to the trachea from the oesophagus both distally and proximally.

Thank you so much this was so helpful ..but the diagrams on board are not visible please show closeups

[@svivekvardhan66]

a legend once said “ let’s begin at the beginning” lol i really love that you start everything from blastula and stuff

[@minass]

Haha thanks

[@nethminnn]

Not forgetting that Nicki Minaj analogy anytime soon

[@tamzey8227]

No one is forgetting that😂

[@abdulkareemabaniwonda6763]

2 yrs later & this video is still serving it's purpose. Thank you for making me understand this Dr. Minass 💯

[@its.AliAhmad]

Lord! That Nicki Minaj reference.... I laughed like crazy in Embryology Museum in my Med School and the demonstrator kicked me out 🤦🏻‍♂️😂 Anyways, thank you so much Doc! you made special embryology so easy for me.

[@minass]

Totally worth it 🤣

[@manogyabishwakarma2858]

this is the first time I've understood these scary embryological figures and what they're trying to say in one go. Thankyou so much.

[@davidcotton6797]

Oh my gooodnesss!! haha This video is amazing! I just started med school and embryology seems daunting (especially because it is so confusing to look at words on a page and try to imagine it. This video is not only easy to understand but has me excited to learn more embryology and see why things are the way they are! Thank you @Minass!!!

[@minass]

Congrats on starting medicine and thank you for watching my video David. I had the same problem that's why I made these videos 👌😎

[@oliviahelen4717]

How is it going now?

[@gayvati2879]

Thank you so, so much. I love your way of explaining things and the fact, that they really stay in my head. You are literally saving me from failing my embryo exam. You truly are a savior of med students!

[@Chrysolite-kn3mz]

OOOMMMGGG thank you soo much! Finally someone has to explain what is happening in those animations! Thanks broo!

[@sharaesingh4925]

This video was extremely helpful and easy to understand. Thank you so much!! I love how you would repeat info and recap things while explaining, its extremely helpful, especially for me as i am a slow learner. I look forward to watching more of your videos!

[@alvaroescandela4495]

Your videos are the best resource to learn embriology, i was trying to learn all of these by memorizing everything (worst idea ever) and not uderstanding. Next time my teachers asks me about the rotation of the stomach i'll start by saying "Do you know who is Nikki Minaj ? well..." True legend!

[@minass]

you are the legend for watching

[@zainabhasrat]

[@riyadhatrah]

Bro you make embryo so much easier to learn! Thank you so much!

[@raaghavbageshwar9185]

You know you're doing a fantastic job when my anatomy professor recommended us to watch your video. Thanks for the great explanation!

[@jacksilver2884]

Nicki minaj analogy; creative and fitting. Well done sir.

[@sandeepaniayodhya8049]

Woah this made embryo my new fav!😍😎Truly appreciate ur work dr.minass!!

[@minass]

Thank you so much 😀

[@debj8121]

Thank you soooooo much! You explain it just in a way I needed to understand the embryology. I am really bad with orientation, so I get lost easily trying to understand the 2D pictures in all the embryology pictures. But you repeat the cutting of the embryo and help me get back on track to see how the 2D is shown, I mean, many people might think it is not necessary because they get it naturally (so that is why a lot of resources omit the explanation) but not for me... haha, I have to watch your video several times, not only that I forget the orientation quickly so I have to come back again and again.. Repetition works.. I am finally getting to a more solid understanding because you explain it from blastula in all embryology videos ( which is what I need)...

[@minass]

Yes exactly, thats what I struggled with when I had to learn this from a textbook that was written in half Latin. So I try to make it easier for you guys to understand 👍

[@mikefedorovsky2577]

You are amazing! Thank you for the brilliant and concise explanations!

[@minass]

No worries Mike

[@williampetit684]

You are an amazing teacher my friend and very good at making these complex topics easy to understand! I wish every lecturer would understand why it's important to explain this way, they just dont care about explaining properly enough!

Sir, thank you for making videos about embryology please keep doing it. I have confused about somewhere in this video. I thought that superior part of duodenum is intraperitoneal but you said that it's retroperitoneal in this video.(15:10) just wanted to emphasize it thanks again!

[@attacktitan703]

Thank you! You explained the rotation of the stomach really well!!
