- This session explains the arrangement of the peritoneum based on sketches that trace the peritoneum in a sagittal and transverse orientation. It also provides the embryological basis for the formation of the peritoneal sacs and folds related to the foregut.
00:00 Abdominal peritoneum in a sagittal section
05:34 Pelvic peritoneum in a sagittal section
06:08 Q1
08:28 The lesser sac in a sagittal section
11:43 Q2
12:16 Bare area of the liver
12:51 Intraperitoneal vs retroperitoneal structures
14:05: Q3
14:26 The relation of the posterior vaginal fornix to the peritoneum
15:04 The peritoneum is a transverse section at the level of the T12 vertebra
18:48 Ligaments of the spleen: lienorenal and gastrosplenic
19:02 Q4
19:49 Q5
20:00 The lesser omentum
22:47 Q6
23:02 Q7
23:52 The lesser sac and contents of the lesser omentum in a transverse section
25:37 Embryology: formation of the falciform ligament, lesser omentum and the ligaments of the spleen
26:18 Q8
28:43 Embryology: formation of the lesser sac
After completion of this video session you will be able to:
Trace the peritoneum in an imaginary simplified sagittal section.
Trace the peritoneum in a simplified transverse section oriented to match CT and MRI axial sections.
Describe the layers of the peritoneum: visceral and parietal peritoneum
Understand the subdivisions of the peritoneal cavity: greater and lesser sacs
Classify the relationship of the viscera to the peritoneum: intraperitoneal and extraperitoneal
Locate peritoneal formations: peritoneal ligaments; omenta (greater omentum, lesser omentum, gastrosplenic omentum); mesenteries (mesentery of the small intestine, transverse mesocolon)
Summarize the boundaries of the epiploic foramen.
Sketch the contents of the free border of the lesser omentum.
Illustrate the ligaments of the spleen.
Outline the ligaments of the liver.
Clarify how the growth of the liver divides the ventral mesentery.
Relate the embryonic rotation of the stomach to the formation of the lesser sac.

I cannot emphasize enough how well this lecture had presented! Thank you so much!
A topic that wasn't clearly explained in college has been beautifully done so by this awesome Dr. Akram. Thanks a ton.
Best video ever. Thank you from Hungary!
I only can give a thumbs up. Never got interested in anatomy but the way you explained, drew me till the end of the class. That's why you deserved to be called "SIR". hats off sir. Excellent.
Thank you for your interest!
best description ever! thank you so much! I couldnt understand this for a month! love and respect from Pakistan!
Awesome. This is how anatomy is fun. Please more teachers like Dr. Akram!
We took this in year 2, I am now reusing it in year 3 and I'm sure i'll reuse it again in the future.. thank you so much for all your efforts
Amazing lecture! This is so excellent! I appreciate the integration of embryology--the best way to understand the peritoneal structures (and medicine in general). Why haven't I discovered your lectures earlier when you began? Thank you so much!
@BidhanShah, check the video 15:15-16:00 to answer your question "why the liver is drawn on the left and the stomach on the right?". The reason is to draw a section that has the same orientation as a CT or MRI section because many physicians will be more familiar with axial sections in their practice. In CT and MRI axial sections the viscera appear as if looking at the body from below. In anatomical sections it is the reverse; However, in many anatomy textbooks, imaging orientation is now used.
this video was FANTASTIC and enormously helpful, thank you
Thank you so much from Ukraine, you made it all easy for me, when i listen to you teach i see the need to know more, i see the need to get better. Sukran.
+olanipekun oluwaseun thanks for the comment I really appreciate. Best wishes.
very professional & well presented with detailed illustrations of peritoneum ( both parietal & visceral) correlated with other internal various organs.Very good for studies of how the treatments for various problems resulted from omental cakes and peritoneal cancers concerned for various cancerous patients using natural herbal system and alternative operation system or both applications. Good for further advanced research & development in due course.
Excellent description and easy to understand, Thank you Dr Akram Jaffar,
Brilliant video! Thank you and best wishes.
Thank you so much Doctor ... Very useful explanation. Thank you again.

That's just amazing!! Thank you too much
Amazing explanation thank you so much
Thank you! This really made much more sense than my lecture did!
That's so helpful thank you !
amazing video, i sturggled to understand mesentries before you drew it out, thanks!
excellent and easy to understand
Superb sir... fantastic....
all good stuff, thank you...
finally got it!thank you so much
Doc, even here, as you say, looking up from the bottom, the RT and LFT markings are opposite what they should be, if the vertebrae is in the correct place. The liver will always be to the right of the spine A/P or P/A (looking down Sup/Inf or up from Inf/Sup. You need to reverse the position of the vertebrae & organs forward to back OR change the markings Rt to Lft. Otherwise, everything else is well explained and the directional relationships are correct.
This was done intentionally in order to teach students to recognize sections as they appear in a CT or MRI because these are the sections the students will be familiar with after graduation. An anatomical section shows the section as if looking at the section from above and would have the sides reversed as you clearly noted but an MRI or CT axial section shows the section as if looking at the body from below.
Very clear explanation, more than ,in lecture, in University or medical schools./.
excellent,thank you.
thank you soooooooooooooooooooooooo much dear doctor this was a
great help for me
brilliant video. thankyou!
The triangular ligaments of the liver are part of the peritoneum. They represent folding of the right & left leaves of the falciform ligament. Each leaf folds on itself when splitting to right & left. The left leaf will form a long double fold, left triangular ligament. The right leaf folds on itself at a more lateral position to form the short right triangular ligament; medially, the two layers of the right double fold are separated from each other, thus bordering the bare area of the liver.
Thank you from India!! Very Helpful :)

Many thanks🌻❤🌻❤🌻❤✋
Thank you too
Thanks for all your helpful videos doctor. By the way, do you have any video about posterior abdominal wall, inf. vena cava and abdominal aorta?
I just found it. :))
Good!
Very helpful video,thanks.But I have a question:
What about positon of triangular ligaments of Liver?What are they continuous with or not part of the peritoneum?
What's the name of the peritoneal pouch between the liver & the diaphragm as asked in the red square in the video?
Thank you so much doctor. I cant express how amazing this video is.
just one doubt, what are the vessels that can be seen in the greater omentum?
So nice of you
Omental (epiploic) branches of the right and left gastroepiploic arteries.
wooow its really helpful
thanks alot
Good luck
excellent sir
+srinu gorla thanks
nice.. thank you very much :)
Finally I understood
wow sir,awseome
All the best.
Superb
Thank you! Cheers!
Good presentation

Dr. Akram do you have a video like this just about Retro peritoneum Organs? I'm an Ultra sound student and I can't find anything useful like your videos about retro-peritoneum

In my textbook there is a line which says
Histologically , peritoneum is composed of an outer layer of fibrous tissue , which gives strength to the membrane and inner layer of mesothelial cells which secretes serous fluid.
But my book also mentions
Peritoneum is composed of two layers 1)an outer parietal layer and 2)inner visceral layer
So does that mean outer parietal layer is made of fibrous tissue whereas inner visceral layer is composed of mesothelial cells ?
Grossly speaking, the peritoneum is parietal where it is related to walls and it is visceral where it is related to viscera. Both parietal and visceral layers have the same histological structure: fibrous tissue covered by mesothelial cells.
thanks for the quick & helpful reply
got a question...why is liver on the left and stomach on the right side in that transverse section of abdomen??
Does anyone have the answer to the question enumerate the blood vessels which are located in the following pertitoneal folds, 1 lesser omentum, 2 greater omentum, 3 transverse colon 4 small intestine mesentery?
