Anal canal & faecal continence (anatomy)

[@ANDeoband]

OKAY I'll be honest here. Anatomy had been my most hated subject, until I came across your videos. Honestly, I have never enjoyed it as much ever before in my life!!

[@rollno.608]

Same is here

[@ahmadsyamil7459]

Real

[@AfsalK]

Just please don't stop making videos sir

[@SamWebster]

OK.

[@Pink_ng]

Stating the fact that after coming across to your channel, my sleepy times during studies have converted into the best hours thanks to your videos. 💯 captures attention throughout the whole video. Not even a second worth skipping. Thank you for being the definition of a teacher

[@PassTheSnails]

This does not get enough attention. You deserve a much bigger crowd.

[@picturetheguy]

Is it possible if you make videos on embryology too? That would be so great

[@Bulgaria1975]

I can't thank you enough for your videos! I am doing level 3 anatomy and physiology. It's so simple I don't understand some of the stuff. I need your explanation and anatomical language (and your passion, mostly your passion) and your vast knowledge and etymology ❤️❤️❤️

[@syedamaimuna2577]

After your videos i am loving anatomy…and it is easier before my final exams..thank you sir😇

[@khaldunal-shaheen2370]

ok , that is by faaaaaar , the absolute best dicription and teaching for the issue , and i have been around . hat off

[@sevvalarpacoglu2354]

the fact that you’re hot makes the video even greater and you’re making the anatomy really enjoyable. thanks for all

[@tasneemsaleem]

You are amazing!!! I never imagined anatomy could be associated with hilarious comedy to make it fun to learn. I really enjoyed and learned with clear concepts. look forward to see your videos series about whole body anatomy.

[@SUZABQ]

absolutely beautiful presentation

You are probably my favourite person👑 Thanks for such good explanations and helping out!!!

You're just a Gift. Thanks 🙏.

[@sandradring6265]

Oh my goodness Sam I’m addicted to your videos. You make them so interesting...okay these complicated names fly over my head but I’m understanding the workings of the subjects. I had a rather a lot of polyps removed from my rectum a few years ago and now I work hard to make sure my pelvic area keeps working well. Now I understand what I’m doing any why I’m doing them. Thank you Sam. 😉👍

[@lindakeating8825]

[@EmilySongsChammel]

Amazinggg!! Thank you so much!! I enjoy it so much

[@ANDeoband]

I'll probably hand over my degree to you

[@pika.p]

These factors that are responsible for fecal continence, which of them has the biggest role? Like if you would have to answer it using percentages what would your answer be? Because my teacher asks that on exams and I don't know how to say it in that way using percentages, like is internal sphincter responsible for %50 or smth like that

[@akan1]

Greetings. Excellent. I really understood the anatomy. Thank you, thank you, thank you. I will be watching more. Stay blessed. OL.

[@sadiatarar9092]

Can you please upload a video on the anatomy of the rectum. Would be grateful.

[@lisabenton5712]

I loved the video its very informative. You touched a bit on the muscle movement of the rectum during defecation. Under normal continence. Im having a hard time finding specific information regarding how the muscle contracts during defecation and or urination. Which direction does it go? Toward the perineal body or towards the tail bone? I have found that the external anal sphincter drops 2 to 3 cm. I just need to know while voiding what that would look like. How it contracts and or moves to allow voiding. If you could help, would be greatly appreciated. Ty

[@zannatul23]

Loved every second of your video, much appreciated sir

Sam Webster Thank you very much Sir for replying please ask your colleagues to do something for pathology, surgery as well in coming months...

[@wazirmedico1524]

[@arun3757]

Do u suggest lateral internal sphincterotomy if involuntary muscle also controls the bowel movement along with other two.

Hello👋 Want you to know.. That its fant what you do.. Thank you so much for that. Best wishes Julia

[@walruss111]

How do we pass gas (flatulence)? Meaning how do we know that it is gas not feces that are in there before we pass it? There must be a way by which the body discerns between gas and solid/liquid in rectum

[@SamWebster]

That’s the job of the stretch receptors in the rectum. Stool will trigger the stretch receptors (and eventually the defecation reflex) whereas gas and liquid stool do not stretch the rectum in quite the same way.

[@lstrawaya6403]

Thank you sir 💕

[@lesleysprake1045]

Have a good night !!!

[@abdulrahmans.3129]

Thanks for the superb explanation! I am wondering, around 16:40 -ish when you talked about venous backflow at the portosystemic anastomoses, I thought you were going to talk about varices and was surprised to see you mention hemorrhoids instead. As far as my very humble knowledge goes, varices and hemorrhoids are somewhat similar in clinical presentation (both are enlarged veins) but their pathophysiology is distinctly different, with varices being attributed to portal hypertension e.g. cirrhosis while hemorrhoids are due to loss of fixation of the anal cushions, and they are not necessarily more common in patients with portal hypertension. Let me know what you think and correct me if I am wrong!

[@paulshuttleworth6261]

As you say. God forbid you discover they are rectal varices halfway through a haemorrhoidectomy! Would be a messy situation.

[@janabailey1177]

You are Wonderful!

[@nafiznasser968]

You are the only person in this world on KZbin describing function of anal cushion. Can you help us to banned Stapled Hemorhoidctomy procedure in which the anal cushion is cut leading to fecal urgency and stenosis. Due to stenosis of sphincter muscle patients have to do Sphincterectomy leading to incontinence. Conventional Hemorhoidctomy is the gold standard for internal hemorrhoids and not Stapled Hemorhoidctomy.

[@DiecastTz]

7:44 loooooool

[@bil7024]

Hope you had fun at the party

[@NSiFe]

And you also got the puboanal!

[@Here_The_King_of_kings]

nice

[@marinapieri4086]

I understand that vascular anal cushions are hemorrhoids. If these have a pathology problem then its more difficult to poop . Is that considered good for fecal incontinence?

[@nafiznasser968]

Sir, does anal cushion grow back after it is cut by stapled hemorhoidctomy ? Or is it a lifetime disability of fecal urgency ?

[@michaelmoleele1754]

well the last part killed me

some exercises for this problems?

[@lyankyinpannyar5106]

you look handsome sir!!!

[@nafiznasser968]

Hello, I found a point on the lower left buttock which u can push or massage during hard stool. U will feel stools passing there and can touch the expanded anal canal on the lower left buttock when stools pass there. When seated during defecation the stools pass the anal canal which is located on your lower left buttock - on the right half hand side. Once you push that expanded part or massage forward the stools will excrete easily.

[@SUZABQ]

viscosities - that is the word you were looking for. Viscosities of poop.

Please reply to me urgently. When you expel stool, does the anus form a ring and become prominent when stool are exiting? Is that the normal physiology or I have anal prolapse!? Your reply will save me travelling to the doctor and embarrassing myself

If have bad gas, you need to do flexible sigmoidoscopy
