 So this is the supine cadaver. This is the right side of the cadaver is the left side camera person is on the right side towards The legged salient parts about the small intestine We have removed the large intestine so and the small intestine is being held up by my assistant here Now my assistant is cutting open a segment of the alia And you can see how steady her hand is Because she wants to be a surgeon. Did I tell you that and she's cutting straight with the curbscissor which is a hallmark of a surgeon Okay Okay, that's enough. Now, let's have a look at the interior Hold up here Yes, I need somebody to hold I have another R24 set there bring the other one from there My assistant has opened up a segment of the terminal alia and we can see straight away after cleaning it up We can see that the mucosal folds are very minimal or almost none That's all we can see that is why Wangenstein has referred the surface of the alia as Structuralist and if you were to do a low microscopic examination of the submicosa We might be able to see pairs patches, but grossly we cannot see any pairs patches So that is what we see in the alia. Now we will open a segment of the Gijinam And we can see that it's got a much thicker wall. So therefore it is taking a little more effort Okay, so now we have reached the lumen Now we are going to open up the Gijinal wall now use the scissors and cut approximately and then cut distilly between the four steps Yes, good cut some more. Wait. Let me put some more Here Cut between the four steps Some more Cut distilly Well, I mean to put the four step inside and direct her Put it inside it. Don't force it. It should go gently by itself Okay, cut Make it easy for her. Yes Cut some more. Okay, so now we have slit open Now again hold the edges for me. Somebody hold the edges for me Hold it out because we are going to put them side by side also afterwards Come on. Come on. Do it. Clamp it What happened Melly, why did you do Now we have cut open a segment of the Gijinam and straight away we can see that the mucosa folds are dense thick and Much more numerous. This is referred to as the valvile conventis or the pleike circularis This is to increase the surface area for absorption And this is the one which when we do a berry meal follow through this gives what is known as a Feathery appearance to the berry meal. So this is a structure feature of the Gijinam mucosa Now we are going to hold a Gijinam mucosa Side by side with an alial mucosa to show the comparison So up here we can see the Gijinam mucosa and then down here We can see a segment of the alial mucosa and when we hold them side by side we can see the comparison So this is Gijinam versus alia Illum is referred to as structuralist Gijinam is referred to as feathery appearance. Thank you very much for watching If you have any questions or comments, please put them in the comment section below. Dr. Sajio Sajio Have a nice day
