Summary of the video for your notes:
1. Pancreas is formed by two buds, the dorsal and ventral buds. They develop from the lining of duodenum.
2. When the duodenum rotates to the right side, the ventral bud moves dorsally shifting itself to the final position of inferior and posterior to the dorsal bud.
3. The parenchyma and duct systems then fuse.
4. The ventral bud forms the uncinate process and the inferior part of the head of the pancreas.
5. The remaining part of the pancreas is derived from the dorsal bud.
6. In 10% of cases, the duct systems fail to fuse and the original double system persists.
7. (Not in video) In the third month of fetal life, pancreatic islets of Langerhans develop from the parenchymatous pancreatic tissue and scatter throughout the pancreas. Insulin secretion begins about the fifth month. Glucagon and somatostatin secreting cells also develop from the parenchymal cells.
Developmental anomaly: Annular pancreas.
- The ventral pancreatic bud consists of two components that normally fuse and rotate around the duodenum so that they lie below the dorsal pancreas.
- Occasionally, the right portion of the ventral bud migrates along its normal axis, but the left migrates in the opposite direction.
- This way, the duodenum is surrounded by pancreatic tissue, and an annular pancreas is formed.
- The malformation sometimes constricts the duodenum and causes complete obstruction (duodenal stenosis).
- Accessory pancreatic tissue may be anywhere from the distal end of the esophagus to the tip of the primary intestinal loop. Most frequently, it lies in the mucosa of the stomach and in Meckel's diverticulum, where it may show all of the histological characteristics of the pancreas itself.

Daamn he's back and stronger than ever! Love your videos man, never stop uploading these please!
I turn to you before approaching any embryology lecture content... THE EMBRYOLOGY HOLY GRAIL.
Omg can't believe I found an easy-to-follow embryo channel O.O!
Very well & simplistically explained. Awesome.
Your enthusiasm in this video finally made this topic interesting. Thank you so much for simplifying this topic
Thank you very much! I´m from veterinary medicine in Germany and was so desperate about my embryology exam. You made my day!
Absolutely amazing! You just taught me what my professors couldnt in about 2 years :D
this was so easy and to the point for me to understand. Thank you. This really helps me for the complexity of my lectures.
Great video, easy to follow and helpful illustrations!
Thank you, sir. You are a legend. A natural born teacher. Thank you for your service to us students.
Thank you! Very clearly demonstrated, will recommend
These are my favourite videos, thanks for making it so easy to understand! ❤

Huge thanks from a french radiology resident!
thanks for watching¬
YOU ARE AMAZING THANKYOU FOR HELPING❤️❤️
this video is very helpfull .. thank you a lot ..very easy and simple now
Thank you sooooo much for this
Nice video illustrations thanks Dr. Minass
Too good, Sir.
Beautifully explained development of pancreas. It will be helpful for me if you explain how exocrine and endocrine component develop. Specially different cellular components of Ilet of Langerhans.
thank you so so much that make so so easy the embryology for me
awesome explanation,thanks alot
Thank you very much!!
amazing job
thank you so much mate, "easy to understand" indeed.
muad elayeb you’re welcome 😎👌
Wonderful lecture thanks alot
This is amazing. Thank you very much :) I am a radiology resident, and was trying to understand anatomy of pancreas. Learning embryology helped me a lot in understanding anatomy in a greater detail.
Cool! Best of luck Sagar
You're so smart and good looking.
i second that.
thank you doc
Amazing!
Love you. Great video and thank you!
Karim Honeineh haha thank you!
Your videos are very helpful mate. Thank you
Cheers!
thankyou now i understand
Awesome explanation
Merci shad Dr. Minas ❤️
My day has been made. Chapen aveli merci 😊
Thanks
I love how you called it a Pokémon looking thing 😂😂😂, now it's gonna be stuck in my memory and I'll remember it forever, I really hated embryology during my first year but it's actually quite interesting if you listen hehe
" this Pokemon looking thing " 😆😆
You caught my attention there
Thank you for this amazing video, I love your clear explanation. very beautiful drawings, thank you for explaining the basic concepts, it is very good for revision
Thank you so much 😀
Thanks you literally saved my time and I nailed my Examinations!!! Keep up
You're very welcome!
Excellent! Could you include in this video another anomaly - pancreas divisium (or many separate anomalies video of pancreas)? Also zoom in from time to time?
Lovely
Love you. thanks
Thanks!
No problem!
Great! Keep it up!
Thanks Loraine!
Thanks for the video! I read that the main pancreatic duct is derived from the ventral pancreatic bud. Does this mean that it grows into the dorsal pancreatic bud after the two buds fuse? Having a hard time picturing it.
He is the Jonny sins of embryology, he rules it
Very helpful
Glad you think so!
Your explanations are so clear Sir
Thank you so much 😊
So easy to understand
Keep up with the good work
Will do, actually aiming for about 4-5 videos this year 🤣
Very useful man
Glad you think so!
Thank you 💕😊
Welcome!
Super!
Thanks Jovana!
Thank you sooo much sir.... actually you made the topic very simple to understand for everyone... lots of love from india 🇮🇳
Love to India back!
I JUST LOOOOOOOVE YOUR VIDEOS
🦋🦋🦋🦋🦋🦋🦋🦋🦋🦋🦋
Much love back! Thanks for watching
Great explanation. Well done
Please upload more medical videos
Lakshitha Galawalage Thanks Lakshitha! I will 🙂
Amazing video, but I'm missing the differentiation of the parenchyma. Anyways perfectly explained, thanks!
thank u so much it s so helpful for me ....from algeria
You're very welcome!!!
how do pancreatic parenchyma differentiate into acini and islets? please explain in detail.
helpful! ★★★★★
Perfect
Thanks for watching!!
can you make some presentation like this about the cellular structure of pancreas ??
Thank you so much, this is incredibly helpful. I just can´t figure out, why the dorsal pancreatic bud seems not to rotate during stomach rotation..Could you help me with that?
there is differential growth between duodenal wall , ventral more than dorsal
Hey Dr
I have a question
Is the ventral pancrea surounded by ventral mesogastrium and the dorsal pancrea by the dorsal mesogastrium.
I'm a bit confused,
Ty
Thanks alot.
My anatomy exam is tomorrow & I was suffering with embryo you litterally saved me💕
Hope you passed!
Yeah actually I did pretty good and all thanks to you&your amazing work❤
I wish you had videos like these all anatomy🙇♀️
Excellent lectures ! Im preparing for Post graduate entrance exam of medical graduates and i find videos very helpful . Cud you please give a lecture on development of gut , mesentery ? Appreciate it.
Awesome, sure the embryology of the GIT are the next few videos I will be making
@@minass thank you doc !
Thanks from algeria 🖤🖤🖤🖤
My pleasure
Do you know when (what week or even approximate day) the pancreas becomes retroperitoneal (i.e., when the posterior leaf of the dorsal mesogastrium and back wall peritoneum fuse and disintegrate)? Sorry if that's a separate subject or overly technical. I figured it's still pancreatic development, and you sound like you might know the answer. :)
Development of spleen 😊 please , this is very helpful thanks
It's coming 😃
You’re so smart and good looking
Thank you for this compliment
Thank you 😍😍 رووعة
Aya Abdi 😊
@@minass where can i find the embryology for appendix ?
Aya Abdi I haven’t made one yet but if you contact me on Facebook I will send you something to help you 🙂
best ever
hala MADRID thank you 🙏
u r wellcome sir

Thank you!
Hey, thankyou for this great video. Can you just answer me the question why only the ventral pancreas moves an the liver still stays?
Thank you an greetings from germany :)
There's a simple answer. Essentially it does that so that the pancreas can develop normally 😂. Otherwise many different anomalies of development occur. Also the liver stays on the right because that's where it belongs. There's no room on the left side of the body for the liver
An Egyptian student passed by here ❤
Kindly please make videos of development of eye, ear, mid gut and hind gut😭
These are all uploaded now!
Thank you for this helpful video, can you please put your Facebook profile link
Added in the description my friend
smart and handsome
🤣
Ur from
australia
He's hot as Johnny sins...lol!
This is not very simple
reticenceof.pain which part. I will explain further
Compared to textbooks and the way my professor teaches, yes it is lol
Amazing !
Thank you! Cheers!
