Today I watched a video on how pissing works. It was very intriguing.

[@zainabalansari3549]

THANK YOU VERY MUCH !!

[@CristyRobin]

Thank you very much!!!!!

[@nolly_]

I had a herniation on L5 - S1 and I cant feel my bladder. I think the Pelvic Nerve (parasympathetic) is damaged :((.

[@yishayeliraz1896]

Thanks a lot! is this interneuron in the end inhibited before voiding? or is the reflex always active ? thanks again

[@dranilkumaraiimspatna]

internal sphincter is present in female and Females do have a more elaborate external sphincter muscle than males as it is made up of three parts: the sphincter urethrae, urethrovaginal muscle, and the compressor urethrae.

[@supboy666]

but it gets weakened post-partum

[@VoidHalo]

I just remembered watching this a few years ago and it was very interesting, so I had to look it up again. incidentally, watching this while I have a full bladder makes me appreciate it all the more. lol

[@Buffalosabskis]

Just watch when you go to empty it. Not too fast

[@giselleleach3556]

I'm a nursing student and even though I don't need to know how micturition works in this much detail, your explanations were just so well-done and intriguing that I couldn't stop watching.

[@cecechannel2]

You should have been taught this in your A&P 2 prerequisite class. How did you get accepted into the nursing program without knowing the basics?

[@zwitterionman2359]

Absolutely remarkable! Thank you so much for posting this. It would also be really helpful if you could briefly describe the pathophysiology of the various types of urinary incontinences.

[@birminghammedics6774]

Thank you so much :) Just a note, some medschools teach that females do have an internal sphincter, as physiologically they do, but anatomically it hasn't been found. Check your course requirements.

[@VoidHalo]

If it hasn't been found is this not conjecture?

[@animeshpathak3921]

I guess for girls the internal sphincter gets weaken as she age.

[@animeshpathak3921]

Same goes for men aswell. Smoking can weaken your muscles.

[@ezgidemir5250]

Now i also shocked because we've learned that females also have internal sphincters, I guess this channel should update their knowledge

[@nupurdogra893]

It is a functional sphincter not anatomical; so it is correct to state that females also have an internal sphincter even though it is not found like a separate structure with dissection like the male one

[@ashtonsneedensequeira8803]

Wow I'm am speechless the best explanation on micturation I have come across love from 🇮🇳 india 😍

[@armandohasudungan]

Thank you!

And back here again in my 2nd year of residency after the last time here was during my premed days, thank youuuu

[@fnz2454]

Only just realised there are faint pencil outlines which he draws over for the diagrams. Anyway, thanks so much! :)

[@PSJish]

Wait, are you sure that both male and female have internal urethral sphincter? Try search it up on google and female KUB system has internal sphincter as well

[@dr.tariqmerestani3027]

Dear Dr.Armando very nice video and explanation. i have a small correction on ur video that the hypogastric nerve is in the Lumber region L2, just to in form the people who follow ur videos including me, and again thank u very much

[@dr.tariqmerestani3027]

According to Guyton 12th edition P312

[@faqihhabib4971]

Tariq Jihad actually he is right, it is coming from toracolumbar region, which is T11-L2 that making hypogastric plexus. CMIIW :s

[@killermakd2015]

The hypogastric nerve enters the sympathetic chain at T10-L2.

[@DrRoughfield]

Dear Armando I am a medical student from Denmark and I enjoy your videoes very much. They supplement my reading very well. I do have a question though about the voiding reflex that you mention in the last part of the above video. You describe it as it is an interplay between the sensory nerve fibers ind the detrusor muscle, the interneuron in the sacral part and the pelvic nerve that makes a loop and ensures continued voiding. As I understood it, the voiding reflex is based on an interplay between sensory fibers in the urethra, not the detrusor. In my mind this makes more sense, in that the flow of urine will keep the urethra dilated and thus stimulate the stretch receptors there, whereas the sensory fibers of the detrusor will not stretch at all during contraction. What are your thoughts on this? Thanks for your time and effort.

[@80sadiayaqoob91]

The best explanation ever💓😍just that the females do have an internal sphincter...but the rest of the video is just outstanding😍💓 may Allah give u the reward for helping students💓

[@thunderr8127]

Why are you unnecessarily mentioning your nonexistent Allah in this?

[@angelajakob1257]

Unlike male anatomy, in which the bladder neck and prostate comprise the internal urinary sphincter, the internal sphincter in females is functional rather than anatomic. So this means that women have a internal sphincters. So according to my source your info is incorrect?

[@shubhamghodke3760]

Omg that diagram is worth million likes 💯

[@karalaalexander7124]

thanks for your vids they are life saving when you have bad lecture notes and good to watch after reading guton book

This is an astonishing presentation. I am casting a wide net I search of a cure for my incontinence 10 months after surgery (NNS RALP/PLND). I’ve found nothing more clear or complete on the anatomy of this topic, including explanations and diagrams from my own doctors and therapists. Thank you!

[@Buffalosabskis]

It's funny. In Med and Bio classes we still need to draw things like this. I am terrible at it, but you are getting graded on the fact that you have an understanding of where everything is. Not how well you draw them

[@muhammadyahya110]

Say Thank you to Mr. Armando by liking this comment 😊... Hats off Armando 👏.

[@borbiharquestions]

@armano I beg to differ. Though you are right about all the nerves. But sympathetic nerves I.e. the hypogastric nerve has little to no role to play in micturition. They are mainly responsible for prevention of reflux of Semen in the bladder during ejaculation. Rest all is fine. Please refer Guyton and Ganong. Thankyou.

[@siddhibhupal1706]

Wowwww just amazingly explained 👏 👌 🙌 👍 😍 ❤ 👏 👌 🙌 👍 😍 ❤ 👏 👌 🙌

[@sweetheart436]

Acids like bad fats and sugars create acidic caustic pH scale to some extent and alkaline is created by Omega fatty acids healthy fats lots of water and fiber humps do that. This directly affects your blood cleaning organs so to speak like your liver and your kidneys, but blood sugar levels in your blood are specifically important to it. This would also be relevant when it comes to alcoholism which is essentially fermented sugar in concentrate which is terrible for your system.

[@Sujeet....]

Plzz 🙏 check your video. In female Internal sphincter persent

[@williambrewer]

What part of the system is messed up in shy bladder syndrome? That is, people are making an effort to pee, but they cannot due to psychological stress.

[@shubhamchaubey.a-257]

Sir please answer me... Does urine act as ecf for depolarisation of stretch receptor present in uri. Bladder if yes Then how depolarisation occur as in urine k+ level is high???

[@hardikpoudel8123]

Think logically guys During parasympathetic u need to urinate so that dextrusor muscle should contract Ok in video its correct BUT Sphincter muscle should be relaxed and nicotinic recepor contracts muscle because its ion gat ed channel So its wrong that it have nicotinic receptor . Please make video by taking a good reference book.

[@sweetheart436]

Not only does a lack of nutrition create a caustic situation for your bloodstream but then adding toxic kind of caustic heavily oxidated protein fats like saturated fat that's bad for you been treated with chemicals, this kind of erodes your arteries but it's not just your arteries your circulatory system goes throughout your whole body and you need the lymphatic system to pump those antibodies throughout your body and white blood cells you have to move your body to do that your limbs like your legs and your arms and as stated a lot of that blood flow is directly clean through those kidneys so your liver and kidneys can be highly taxed and as your blood flows caustically if it doesn't have a good pH it can literally erode your arteries and then the bad fats plaque it up to try and spackle those caustic potholes that they initially created, you don't even have good fats to repair it so it's just terrible you need lots of water alkaline blood lots of fiber fruits and vegetables and you need healthy Omega fatty acids and fish or you know an Omega substitute for something like fish that's packed high and niacin or like flaxseed barrage etc come out drink lots of water it's not that hard and then you need to move your body or at least an hour a day specifically for cardio you don't have to jog it doesn't have to be strenuous it just has to be consistent with the intention of walking at a moderate to brisk Pace you don't even have to pass walk and it's better if you get out in nature to do so I wish you'd let me I'm tired of f****** sleeping all the time having welts on my body and burning my feet at night

[@yourwillieshop984]

Are there any nerves that would sense a tingle/pressure/pleasurable sensation when you really have to pee close to the urethral opening that could be damaged in a cytoscopy or laproscopic hysterectomy?

[@borbiharquestions]

Also micturition reflex is basically a spinal reflex controlled by the central nervous system. So what you say is partly true but not completely. A spinal reflex is started which is facilitated or inhibited by the pontine facilitatiry and mid brain inhibitory areas

[@lingarajpatnaik6514]

? females do not have and internal urethral sphincter ! think it is present .and thats is the the eternal urethral sprinter that is not so well developed --hence increased stress incontinence - please make time to clarify

Hi Armando! My friend and I are studying for our homeostasis exam and we love your videos! You have really helped us :) We have a question though. When we looked at old exams we saw in one of the answers that the sympathetic receptor on the detrusor muscle is an Beta 2 - receptor and not a Beta 3 - receptor as it is in your video. Do you know which one is the correct one? Keep on being awesome please!

Anecdotally, I have degenerative disk disease and lumbar spinal stenosis extending into the sacral region. If I urinate standing up (I am a male age 71) I get post void leakage, even though my bladder feels empty. If I sit to urinate, I manage to get my bladder truly empty as no leakage occurs. Can you explain the mechanics of what is going on in terms of your diagram. Does this invo;ve the Onuf nucleus in S2.
