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.
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!
I'm not a medical student or professional but I have studied human anatomy and physiology, neurology and human behaviour by myself for a number of years now. I'm so pleased with myself because I was able to follow most of the terminology you used and the basic structures. I now need to learn about the efferent and afferent nervous system and various receptors and what happens when the bladder is empty or full (as well as voiding) in more detail, and your video here is just perfect for me to stretch my understanding of the urinary system and micturition. Your drawings are outstanding, as is your commentary! I learned much from you - thank you very much!
Very inspirational, keep going strong my friend. Just a little correction, I know you probably misstyped but just to give you a hand and keep terminology right. There is no efferent and afferent nervous system. You are maybe reffering to sympatic and parasympatic or maybe you are thinking about sensory and motoric pathways? Either way just a small detail, keep going and good luck!
This video is extremely helpful! I would definitely recommend watching before your micturition session for class. It would make understanding pharmacology better!!
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.
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
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.
I think this was left out of my medical school lectures... thank you for making and sharing these so I can better understand urinary physiology, pathology, and pharmacology
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.
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
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💓
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.
You are God sir! Pls keep making more such VIDEOS... The first place I look for a video on a topic that disturbs me is here.. if I don't find a video on that topic by you, I am forced to look elsewhere, but if I do get it here... There's no reason left for me to anywhere else! Your explanation is pure AMAZING and I appreciate you for your hard work! Thank you so much sir! Love from India❤️
Thank you for this explanation, now I understand better that normal functioning of active voiding contractions are initiated by messages of the efferent side of the reflex arc .
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
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
Sir your explanation is incredible and remarkable,, you are genius, I am soo much glad after watching this video, u are great ful, thnkuuu soo much sir, alot of respect for you, incredible job.
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
Thanks for the video. There is no anatomical ground to say female does'nt has an internal urethral sphincter. There physiology in this aspect is even more complicated when going into a discussion of Skene's gland, G spot and squirting.
Great video. One thing I would comment on is that the somatic control of the external sphincter should be coming from the cerebral cortex, not the pons. none the less, excellent explanation.
@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.
I was diagnosed with neurogenic bladder, I urinate frequently, have strong urges to urinate, and my bladder leaks while sleeping, I'm embarrassed because my bedding is wet with urine sometimes, I have cerebral palsy as well

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?
the finest explanation i even seen, with awsm digrams and handwriting ❤ take love from India❤
@Wells Miles plpppp0
Shi m mja gya bhai 👌
And back here again in my 2nd year of residency after the last time here was during my premed days, thank youuuu

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

why do you study it? really inspirational thhough
This is helpful, thank you

I think females do have an internal sphincter although it is a less elaborate structure
Armando, hats off, to the casual, non chalant, but confident way, you draw figures. Furthermore, your accent seems to have improved. Kudos !!!!
This video is extremely helpful! I would definitely recommend watching before your micturition session for class. It would make understanding pharmacology better!!
Galat hai bhai mai neet ka student hu. In female Internal sphincter persent
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.
If it hasn't been found is this not conjecture?
I guess for girls the internal sphincter gets weaken as she age.
Same goes for men aswell. Smoking can weaken your muscles.
Now i also shocked because we've learned that females also have internal sphincters, I guess this channel should update their knowledge
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
Thank you. A massive improvement on Gray's anatomy book 60 years ago. Fantastic refresher course.
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.
I think this was left out of my medical school lectures... thank you for making and sharing these so I can better understand urinary physiology, pathology, and pharmacology
thanks for your vids they are life saving when you have bad lecture notes and good to watch after reading guton book
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.
but it gets weakened post-partum
Best best best lecture ive ever been through on this app ... much blessings and prayers your way as a reward of this lecture.
May God bless you more .
excellent explanation , with very high standard pics and absolutely clear concept ,hats of ,keep it up
Sir, you should be rewarded for this masterpiece!! I'm speechless and idk how to thank you enough, god bless you❤
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
Just watch when you go to empty it. Not too fast
Better explanation than given in First Aid.
Thank you 👍 and pray for my exam..
I'm a medical student, and I love your videos. Can you make some pdfs available of your finished diagrams? That would be incredible!
in which grade, are uhh?
Can't believe i spent 2 hours reading about this when it was taught so well in 15min !
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💓
Why are you unnecessarily mentioning your nonexistent Allah in this?
I just know our senior clinician watches your videos because she had the exact same drawings on the board today

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

Ur diagrammatic explanations are really very helpful to understand the concepts better.ur teaching is just awesome sirr.
Thank you so much. I think i learned from you more than any professor in med school!
An easy and well explained video.
Thanks from Bangladesh 🇧🇩
Galat padhai rha bhai
Thank you for this explanation, now I understand better that normal functioning of active voiding contractions are initiated by messages of the efferent side of the reflex arc .
We need to call you the good and the greatest teacher in the world 😍😍😍thank you sooooooo much 🧖♀️👏👏👏
Amazing clarity!
May you enjoy great health and happiness!
Omg that diagram is worth million likes 💯
This Is the best video I've ever watched about micturition🙌🙌💯💯💯.. Thank You very much🤗.
Really it is the best explanation for micturition physiology I have ever read.
thank you so much, how can this video not going viral
Excellent, complicated process made super super easy, thank you very much
Armando Hasudungan saving lives since 1989
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
According to Guyton 12th edition P312
Tariq Jihad actually he is right, it is coming from toracolumbar region, which is T11-L2 that making hypogastric plexus. CMIIW :s
The hypogastric nerve enters the sympathetic chain at T10-L2.
Well explained 👏
Hope that you also include how does the case of micturition syncope happen?
I have two questions
1.Do people use abdominal pressure to urinate?
2. when we urinate ,If we stop urinating by using our muscle , what happens?
I think there is no other way to explain better than dis ......u r d best...... thank u very much Armando 😍
The best explanation is ever seen.. So far
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

thank you :)
@@armandohasudungan you are emotion for me your voice takes me to my mbbs days memories..
Great thankful 😊
Sir your explanation is incredible and remarkable,, you are genius, I am soo much glad after watching this video, u are great ful, thnkuuu soo much sir, alot of respect for you, incredible job.
Such an extraordinary tutorial. Thank you so much sir!
It helped me a lot .. My presentation was appreciated because of this videos.
Life saver❤ amazing diagram and crystal clear explanation 🥺🥺❤
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
Love from India….best explanation till ever
Galat padhai rha bhai
Thank you sir
love from Malaysia
Loved your video. You've made it simple and easy to understand. For me female pelvic structures and functions is basic....Great content, 👏🏽
Simply amazing explanation 🙇
Thank you so much 🙌🙌🙌 the concept went and sat straight in my head! 🎉
Very good. Clear illustration.
Thanks alot for this great explanation but u forget the role of cortical control center and its role in the micturation
This was so helpful 🇿🇲
Thanks for the video. There is no anatomical ground to say female does'nt has an internal urethral sphincter. There physiology in this aspect is even more complicated when going into a discussion of Skene's gland, G spot and squirting.
Brilliant, can you make some videos about the results of spinal cord lesions at various levels
Excellent diagram and explaination
Exciting and to the point explanation , good job
Wonderful presentation sir
exceptional!!!
its strange that the micturition has remained the same after 7 years:))
You are a hero to mankind, and I will nominate you for a nobel prize on education
He deserves to be nominated.
Please please please please sir make videos on cancers with their treatment in full detail
Wonderful and it is enough that it reminds us with classic teaching
A.....M...AZING SIR.......NO WORDS, SIMPLY THE BEST
I'd develop interest in Urology if lectures are of this quality!
Thank you sir. Now it will be easier for me to understand the text in Guyton.
Very Interesting as well as your teaching skills are Excellent thank you.
Galat padhai rha hai bhai
So far the best explanation!
You are the best, armando.. appreciate
Great video. One thing I would comment on is that the somatic control of the external sphincter should be coming from the cerebral cortex, not the pons. none the less, excellent explanation.
Beautifully explained....
Beautiful diagrams...
Thank you very much 🙏🙏
This channel is one of the best 🫶🏾❤️
Thank you for saving us

That afferent pelvic n. had me confused for a long time. Thank you!
Clear concept and with awesome diagrams.... thank you so much this helped me a lot...
I SAW THE PENCIL LINES! lol you're still the best.
super informative! thank you so much! maybe you will create an additional video that helps explain why sometimes urinating feels so close to orgasmic?
Excellent explanation.. 👍👍
Good evening sir,But I would like to tell you that females do have internal sphincter located within the walls of the urethra
Thank youi for the Great Video.
best video i have ever seen
Armando, this video is amazing. Do you have one on defection as well as micturition?
Blessings Sir. well explained.
Your video just made this a whole lot easier for me!!! Thanks
THANKS FOR HELPING ME UNDERSTAND THIS TOPIC
studying medicin in germany.you explain it much better ! thanks
I subscribed ur channel❤ I'm studying nursing...
I was diagnosed with neurogenic bladder, I urinate frequently, have strong urges to urinate, and my bladder leaks while sleeping, I'm embarrassed because my bedding is wet with urine sometimes, I have cerebral palsy as well
what a wonderful talk.
Amazingly clear explanation! Thank you
Wowwww just amazingly explained 👏 👌 🙌 👍 😍 ❤ 👏 👌 🙌 👍 😍 ❤ 👏 👌 🙌
Excellent.Explained with great clarity.
very simplified and easily understood..must watch
