Beautifully explained, studying for my NP2 exam and was really struggling to grasp the various pathways of emesis. Highly appreciate as now I get it. Thamk you
Your clear explanation, excellent drawing skills, right speed and tone of voice contribute to your great presentation of vomiting physiology that this ICU and Postanesthesia Nurse now fully understand.
I’m gonna give a presentation🧑🏻🎓 in my Uni tomorrow(the topic is vomiting🤮) and your video seemed extremely helpful🤗 to me..Thanksssss bro🥰😘 And a big applause 👏🏻for the art of drawing ✍️ .Awsome.Keep it up
We know Nausea and vomiting of pregnancy usually starts before 9 weeks of pregnancy. For most women, it goes away by the second trimester (14 weeks of pregnancy). For some women, it lasts for several weeks or months. For a few women, it lasts throughout the entire pregnancy. I was fed off because of nausea during my pregnancy, I couldn’t put anything inside but when I found “no to morning sickness tea” it works like a miracle for me.
Still waiting for the Pharmacology Video. Great Channel and amazing way of explaining such complex topics on a easy and simple way. Great Job! STILL WAITING FOR THE PHARMACOLOGY VIDEO.
Do make a video on :- 1. Vestibular system and functions 2. Inner ear anatomy and physiology 3. Vertigo types and assessment 4. Semi circular canal anatomy thanks & regards
What an excellent video and explanation! Thank you soo much for providing this. I was very disappointed to see the pharmacology video you mentioned was never made or not uploaded? Please can you do this/upload it?
Hey dude, I've mentioned this before but I truly believe your videos would be so much better if you had english subtitles. It's just another way of getting info into the head. Love your work!
How exactly does the Vestibular Cochlear Nerve activate causing motion sickness? From what I understand, the VCN transmits orientation information derived from the Vestibular Organ. From other sources, it is the conflict between the information sent via the VCN and the information sent by the Optic nerve that create the Motion Sickness. Attempting to read a book while in a moving vehicle creates movement information transmitted via the VCN from acceleration activating the Vestibular Organ while the lack of movement in the visual field creates stationary information transmitted via the Optic Nerve. How does the Vestibular Nucleii activate the Vomiting Center? The Vestibular Ogan senses acceleration (change in motion) so how does and why would it send vomiting signals? What is the purpose of vomiting when you are in motion? If the optical centers work collaboratively with the Vestibular Organ to create motion sickness, what is that sensation for? What is the purpose of evacuating the gut when the eyes and ears disagree on whether the body is moving or not? If there is no purpose, then is it merely an accident of evolution for the brain to process movement information from two sources and erroneously initiate the vomit processes?
I have a question and I will thankful for anyone who answers it: What is the difference between Area postrema and the trigger zone? Is the trigger zone part of the area postrema or is it an extra center? How does the signal flow through these 3 places in this case? Thanks.
+Delena Fan as i understand it, the chemoreceptor trigger zone (crtz) is part of the area postrema (AP). The AP has connections with the afferent fibres of the vagal nerve, so it can sense vagal stimulation. It also connects to the NTS en the motor nucleus of the vagal nerve. The stimulation of the NTS by the AP can induce the vommiting.
Thank you! I’m trying to figure out why I’m having quick onset nausea then projectile vomiting that is unrelated to food injestion or emotional or visually stimulated that within 5 min results in becoming unconscious and incontinent. At the age of 61 it has now happened 4 times once 2 weeks apart up to 8 months between episodes. I am a retired RN. Complete GI work up was negative. No vasovagal type pre sensation. CT of brain negative. EEG pending. Hospitalized 4 times without answers. Hx of a STEMI 1 1/2 yrs ago. But STRESS test and triponin levels last episode this week were normal.
Sir thanks alot for your explanation. Kindly make video for managing ph urea creatinine and by controlling things how csn we make protocol to avoid dialysis.
I suffer from daily nausea and Ondansetron works well. The HTP3-receptor antagonist, serotinin antagonist. Antihistamine didn't work neither did Metoclopramide or Domperidone. I already knew about the CTZ and vomiting centre. But not that it is only the vomiting centre is the one causing the vomiting to happen. I thought it was possible to vomit without the help of the vomiting centre. Is it possible to get the vomiting centre removed? Or shut down completely? And will that result in not vomiting anymore for the rest of you life? That would fix both my gastroparesis and my emetophobia. I don't believe there's a doctor who is able to do this though. The place where the vomiting centre is located is very hard/impossible to operate on I guess. Or might this be happening one day? I love the video by the way!
Nice video but what I'm looking for is a video of this. Trying to explain to my daughter how she got sick. Thought a video would help.Maybe you could make one.Would a video of someone Puking while getting a CT scan?
Hey guys this is Nerdyboy and i want to let you know that dont ever eat jelepeanos because if you do you will get really sick like i was yestarday and i feel a little bit of sick still so try to avoid if you can Nerdyboy is out.
my book says that vestibular apparatus doesn't stimulate the CTZ but directly the vomiting center, and the Stomach and intestines stimulate the CTZ not directly to the vomiting center?
Copied this from Rang and Dale textbook. "The CTZ receives inputs from the labyrinth in the inner ear through the vestibular nuclei (which explains the mechanism of motion sickness) and vagal afferents arising from the GI tract. "
i read from articles there are 5primary afferent pathways -> vomiting: vagal, vestibular, CTZ, cerebral cortex (is this what you called higher cerebral cortex?) and midbrain (where is it in your video,can you help me..) thanks alot
Hey may I ask you how you shoot your videos? Like where do you place the camera and stuff? I've been wanting to make a video and your usual angle in your videos is just what I need! Hope it's not too dumb of a question... Thanks!
How come I get nausea, even some sort of stomach sickness, feel exactly like I'm going to throw up, and it never happens, as it just turns out to be diarrhea a few hours later. I have not thrown up in 7 years.
I assume it's based on the redirection of blood flow when working out. In short, digestion is highly energy intensive on the body and thus requires a great deal of blood flow to be redirected to the necessary organs (same reason why when you eat "too much" you get lethargic and want to sleep). Exercise also requires a great deal of energy and blood flow so when you workout your blood is redirected to the corresponding muscles to maintain performance making digestion inefficient. Sensing this the body will sacrifice the food in the stomach (forcing you to vomit) since it's not being digested and blood is still required to go elsewhere. Also it's important to note that eating something small before working out is good depending on when and to what intensity you will be working out. Your body will draw on that food for energy as long as it can balance the digestion with sustaining muscle performance. I hope this helps and I defer to anyone that has a more specific answer or if I got any of that wrong but that's my understanding of why exercise induced vomiting occurs.
Adhlere Coffy agree with you! Also, as the blood flow redirects to muscles and the food stays at one place for a long time, probably it will end up causing too much irritation and thus inducing vomit. Even more if it's in the most proximal parts of the tract (stomach, duodenum). Have a nice day! :)
What about vomit through emotion? Like when you're so shocked / hurt that you feel / get physically sick? How does the emotion connect to the vomiting centre?
According to my book "pharmacology" by rang and dales, it is the higher cortisol centres that deals with emotions, just like pain and repulsive sight or smell. :)
Hello. Once I saw in "medical detectives" that if someone is being asphyxiated with a pillow, said person vomits in order to try to clear the air path. Is the higher center responsible for this emetic reflux? Thanks for your videos.
I was feeling sick today after eating a lot of greasy foods. And I kept telling myself, I’ll be fine, I won’t vomit while spitting out swimming pools of saliva. I got myself a sprite thinking I was going to feel better afterwards, 2 minutes later I ruined the bathroom. Sprite and anything acidic is good for stomachaches. Edit: is it normal to be shaking so much after everything happens?

You make my life in PA school so much better! Thank you! :)
awesome video. helped my autistic daughter understand why her "stomach doesn't want anything to eat or drink"! Thank you!!
Your clear explanation, excellent drawing skills, right speed and tone of voice contribute to your great presentation of vomiting physiology that this ICU and Postanesthesia Nurse now fully understand.
I’m gonna give a presentation🧑🏻🎓 in my Uni tomorrow(the topic is vomiting🤮) and your video seemed extremely helpful🤗 to me..Thanksssss bro🥰😘
And a big applause 👏🏻for the art of drawing ✍️ .Awsome.Keep it up
Would you consider posting a PDF of what you've drawn so I can download and print it? I can't draw as well as you :)
i bunk classes all the time and still score good marks. one of the reasons is you mate.
Thank you so much! This was amazing! Before this, I was so confused about how all of the parts worked together and where they all were
Just amazing! I teach final year pharmacy students; and in the Oncology Module, this video proves invaluable. Thank you so much!

Amazing video. You can also add the increased intracranial pressure in the stimuli that result in vomitting.
nice explanation for beginners of the Medical...
excellent video. where can I find the pharmacology part of this video?

Armando! You are a life saver, I love your videos
Nice explanation 👌 easy to understand
Very nice video but i think you have completely missed describing about the NK receptors. They seem very important in the pysiology of vomiting
Do make a video on :-
1. Vestibular system and functions
2. Inner ear anatomy and physiology
3. Vertigo types and assessment
4. Semi circular canal anatomy
thanks & regards
Thanks a lot
Waiting for the Pharmacology part.
What an excellent video and explanation! Thank you soo much for providing this. I was very disappointed to see the pharmacology video you mentioned was never made or not uploaded? Please can you do this/upload it?
Another GREAT video as usual, thank you
Plz upload the pharmacology part
Thanks sir. please do update on pharmacology part. keep up the awesome work.
8 years later video still valid
Very educational and informative. Was curious about the physiology behind it as I'm suffering from a horrible hangover at the moment!
Hey dude, I've mentioned this before but I truly believe your videos would be so much better if you had english subtitles. It's just another way of getting info into the head. Love your work!

but, where is the pharmacology part of this video ??
Here is only physiology of vomit Mr.....
Thank you, incredibly helpful!

This is just simple and understandable , thank you
thanks man i love you !! :) keep the explanations coming you are teaching a generation of Future doctors :)
You mentioned a following video about treatment, when will this go up? It'd be incredibly handy for finals in a month
Sir thanks alot for your explanation. Kindly make video for managing ph urea creatinine and by controlling things how csn we make protocol to avoid dialysis.
Sir fan of your explanation and more things to know
I have already made many points and now asking your help regarding potassium and ph.sodium is not an issue for me
Nicely explained. Thanks

can you upload the papers of all videos in pdf file and i will print it ..that's wil help me
superb video, enjoyed
Hi: is the Emetic REFLUX or the EMETIC REFLEX?
my book says that vestibular apparatus doesn't stimulate the CTZ but directly the vomiting center, and the Stomach and intestines stimulate the CTZ not directly to the vomiting center?
that right
yup ! actually the inner ear will stimulate the cerebellum which will eventually stimulate the the emetic centre
Copied this from Rang and Dale textbook. "The CTZ receives inputs from the labyrinth in the inner ear through the vestibular nuclei (which explains the mechanism of motion sickness) and vagal afferents arising from the GI tract. "
Excellent, grettings from Peru, What literature do you read to do this video?
i love the rap intro at the beginning XD
thanks Armando..
I enjoy watching your videos, I wish you draw a person vomiting as well.
Love your drawing btw !
i read from articles there are 5primary afferent pathways -> vomiting: vagal, vestibular, CTZ, cerebral cortex (is this what you called higher cerebral cortex?) and midbrain (where is it in your video,can you help me..) thanks alot
Thanks so much
amaizing vedio amazing explination. 10/10

Great video. Thanks.
thanku so much
Thanx for this vid is this the Area postrema?
How come I get nausea, even some sort of stomach sickness, feel exactly like I'm going to throw up, and it never happens, as it just turns out to be diarrhea a few hours later. I have not thrown up in 7 years.
Is that bad? Or does it just mean I have a good stomach?
Thank you!
good job bro
Supportive video...........thanks

What can someone do if they suffer of nervous/anxiety vomiting? And also to prevent the clogged and gagging sensation in the thoroat?
Thank you so much for this.
+Aleah Abegail Saligan welcome :)
How about the Phrenic nerve and its part in vommiting or regurgitating?
I was feeling sick today after eating a lot of greasy foods. And I kept telling myself, I’ll be fine, I won’t vomit while spitting out swimming pools of saliva. I got myself a sprite thinking I was going to feel better afterwards, 2 minutes later I ruined the bathroom.
Sprite and anything acidic is good for stomachaches.
Edit: is it normal to be shaking so much after everything happens?
good job thanks
Excellent...thank you.
Thank you :)
One question, is vomiting related to Histamine 2 Receptors too?
Nope, it related to Histamine type 1 receptor....type 2 receptor is for peptic ulser
@@self6136 thanksss, I already finished college, but really appreciate your reply
hey can u please come up with embryology videos...ur drawings and your style will be best to understand that...
Are you sure that vestibular nucleus activates CTZ and not vomiting center directly?
Armando Hasudungan Sir.. where is the pharm video put up? Urgent..
Hey you did not mention anything about the receptors present in gut .
I can understand getting rid of toxins but why would activation of vestibulocochlear nucleus cause vomiting? What is the rationale?
thx very helpful.
What is differences between Central and Peripheral vomiting ?
Thanks so much, this is great. I heard that pathology causing the heart to stretch causes vomiting too. How so? Is this vagal stuff again?
btw love your style of drawing haha. Thanks for the video ;)))
Good one but where can I find the pharmacology drugs use for emetics please.
Amazing, thank you👌
