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!
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
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!
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.
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.
This video is extremely helpful! I would definitely recommend watching before your micturition session for class. It would make understanding pharmacology better!!
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
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.
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💓
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
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 .
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.
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
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?
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.
@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.
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
🧠 TEST YOUR KNOWLEDGE FROM THIS LECTURE! ✅

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

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

why do you study it? really inspirational thhough
This is helpful, thank you
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
And back here again in my 2nd year of residency after the last time here was during my premed days, thank youuuu
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.
Thank you. A massive improvement on Gray's anatomy book 60 years ago. Fantastic refresher course.
thanks for your vids they are life saving when you have bad lecture notes and good to watch after reading guton book
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 .
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
Sir, you should be rewarded for this masterpiece!! I'm speechless and idk how to thank you enough, god bless you❤
excellent explanation , with very high standard pics and absolutely clear concept ,hats of ,keep it up
I think females do have an internal sphincter although it is a less elaborate structure
An easy and well explained video.
Thanks from Bangladesh 🇧🇩

Armando, hats off, to the casual, non chalant, but confident way, you draw figures. Furthermore, your accent seems to have improved. Kudos !!!!
Better explanation than given in First Aid.
Thank you 👍 and pray for my exam..
Amazing clarity!
May you enjoy great health and happiness!
Ur diagrammatic explanations are really very helpful to understand the concepts better.ur teaching is just awesome sirr.
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?
Well explained 👏
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
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?
You are God sir! Pls keep making more such VIDEOS...

Thank you so much. I think i learned from you more than any professor in med school!
Excellent, complicated process made super super easy, thank you very much
Can't believe i spent 2 hours reading about this when it was taught so well in 15min !
I think there is no other way to explain better than dis ......u r d best...... thank u very much Armando 😍
It helped me a lot .. My presentation was appreciated because of this videos.
Love from India….best explanation till ever
Galat padhai rha bhai
Only just realised there are faint pencil outlines which he draws over for the diagrams. Anyway, thanks so much! :)
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.
studying medicin in germany.you explain it much better ! thanks
Life saver❤ amazing diagram and crystal clear explanation 🥺🥺❤
Really it is the best explanation for micturition physiology I have ever read.
This Is the best video I've ever watched about micturition🙌🙌💯💯💯.. Thank You very much🤗.
Such an extraordinary tutorial. Thank you so much sir!
We need to call you the good and the greatest teacher in the world 😍😍😍thank you sooooooo much 🧖♀️👏👏👏
Beautifully explained....
Beautiful diagrams...
Thank you very much 🙏🙏
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?
Simply amazing explanation 🙇
Armando Hasudungan saving lives since 1989
Exciting and to the point explanation , good job
The best explanation is ever seen.. So far
Loved your video. You've made it simple and easy to understand. For me female pelvic structures and functions is basic....Great content, 👏🏽
Very Interesting as well as your teaching skills are Excellent thank you.
Galat padhai rha hai bhai
Omg that diagram is worth million likes 💯

That afferent pelvic n. had me confused for a long time. Thank you!
THANKS FOR HELPING ME UNDERSTAND THIS TOPIC
So far the best explanation!
Thank you sir. Now it will be easier for me to understand the text in Guyton.
Amazingly clear explanation! Thank you
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
very simplified and easily understood..must watch
Excellent diagram and explaination
Thanks alot for this great explanation but u forget the role of cortical control center and its role in the micturation
You are a hero to mankind, and I will nominate you for a nobel prize on education
He deserves to be nominated.
please make a vido about the juxtaglomerural apparatus and the renin angiotensin pathway
You sir, are incredible. Thank you for the upload.
what a wonderful talk.
I just know our senior clinician watches your videos because she had the exact same drawings on the board today
Your video just made this a whole lot easier for me!!! Thanks
Wonderful presentation sir
