This is helpful visual information. I'm a 40-year survivor of cancer in the nasopharynx with severe, and still- worsening, swallowing & eating difficulties - thanks to damage from tons of radiation & chemo. With no real help from the medical community, I've started my own research & proactive approach to finding some relief. This video has helped me gain a little better understanding of what's going wrong.
You’ve got my full attention . Truly, I’m having my grandchildren watch this too. They’ll enjoy learning from this also. Again, thank you so ver much for your thorough insight.
This was great, I have been researching "how do i know if my shingles are healing?" for a while now, and I think this has helped. Have you heard people talk about - Paneah Nonpareil Paramountcy - (do a search on google ) ? It is an awesome one of a kind guide for discovering how to get rid of your shingles without the normal expense. Ive heard some super things about it and my neighbour got amazing results with it.
This is an excellent presentation. I'm about to finish up a dissection of the pharynx and larynx and this is helping solidify and increase my understanding.
you are incomparable DR JOHN BOLTON ! YOU HAVE SUPERBLY ELUCIDATED AND DEMYSTIFIED THIS WHOLE CASCADE OF SWALLOWING ! LONG LIVE DOC AND CHEERS !MAY THE OMNIPOTENT GOOD LORD BLESS YOU WITH MORE LIFE!I LOVE YOU SIR.
Just preparing myself for my phoniatrics exam, this helped me a lot! You are really talented in explaining and teaching in a comprehensive way! Thank you!
What an excellent teaching it is. Thank you so much. so clear, organized, I am so impressed. I learnt it so well after watching this teaching. Thank you so much.
This is so good. I was diagnosed with Esophageal cancer in Feb 21 after doing a Barium test and and endoscopy. They found Barrets esophagus. My food pipe was so badly damaged, I couldn't swallow hard meats. I hiccupped and coughed when I tried to swallow. Luckily they found it early and I received chemo radiotherapy then surgery and now I am receiving immunotherapy. God willing it won't come back.
AS a physician ,i must congratulate you for an excellent presentation (Anatomy & physiology) very well done made me to remember all the cranial nerves again!! Harry Sastrty
Hello Dr. Campbell Excellent popular presentation of swallowing mechanism. I believe Glossopharyngeal forces pushes bolus all the way to the anterior cervical spine and that turns bolus downward and then Autonomous forces are taking over. I believe this is important stage of the swallowing mechanism. If anything interferes with Glossopharyngeal forces then we Dysphagia cowman problem with Anterior Cervical Fusion. With all respect. Dr. Zarije Djurovic
Dr if may be a tonsil gets generated by some abnormal activity of body large enough such as a large bolus and that after oesophagus expands due to which wouldnt let the epigllottis to be open , then what would be cure of this .
Great video! I don't have much knowledge of medicine, but the material was so clear and interesting that I watched it all (I came here only to check how the food doesn't get into lungs). However, one thing remains unclear - does it work the same way with drinks? There are people who are able to drink really fast. Are they able to turn off the first stage of deglutition and swallow it without pressing their tongue to the hard palate (I was unable to manage to do it myself)? If so, does the epiglottis closes during the process, or the closing reflex is somehow triggered by the tongue movement to the hard palate?
+Zilvinas Steckevicius For sure the epiglottis must close, or the fluid would run into the lungs. While some people may learn to modify the voluntary components of the process, the process for drinks and solids is essentially the same.
Dr. I have a question, doesn't the larynx moves superiorly and anteriorly (hyolaryngeal excursion) in order for the epiglottis to attach to it? Could you please explain more about it please? Do you also have a video about dysphagia?
dont you think that both elevation of soft palate and contraction of posterior pharangeal wall -also- are togather the reson of closure of nasal region? ☺
could you tell me, in regards to the vagus nerve specifically what branches are used for the sensory sensation and which branch/es is used for the motor activity of the swallowing process? Many Thanks
Nice..if nerve supply was also shown along with afferent n efferent pathways along with associated disorders it would have been more helpful.very nice presentation though.thanks
Sir ur videos are the best but sir I am having problem to understand trachea oropharynx laryngopharynx nasopharynx can u make a video on this? I really need ur help sir
Hi, Thank you useful for my lactation exam. Do you know why the soft palate and the novela dono do their work completely with some breastfeeding babies. It is not unusual to see milk coming out of the nose in some babies even when the hard and soft palate is intact?
Cough has many causes and you need to see your doctor. However, does you dad have any problems with acid reflux from the stomach? This is an often overlooked cause of the form of cough you describe.
Hi doctor what is the mechanism that occurs when you are swallowing and laughing at the same time and get choked , which is the principal dysfunction , which sphincter or muscle get relaxed allowing the food go to the respiratory compartment?
Hi sir ,thanks alot great... explanation,many times i faced choking sometimes during eating or sometimes drinkings cold drinks .....plz help me ...my breath became totally closed for 3 to 4 mints ...its so horrible, after taking long burp i feel relax and my breath become normal .its happend with many times....why its happening me with
Dr. Campbell, my daughter has suffered vermian hemoragia due to AVM. Now, she is cannulised (tracheotomised). And we pull out the air in the cuff, she aspirates a little.I think there is a little problem at 9. cranial nerve. What can I do except waiting?
+ikua EREN Im sorry your daughter is so unwell, if she has a tracheotomy, your doctors and nurses will be able to manage her airway very well. They will prevent her from aspirating by doing tracheal suction. I do hope she makes a full recovery.
Respected sir...u explained how the food goes in...and explained movements occurring at orophyrnx and laryngophyrnx...but you dont explain how it is happening...???thay was a bit terrible..

How and treatment of renal failure occurs
After a stroke and dysphagia occurs, does the autonomic nerve get damaged leading to people unable to swallow?

Many Thanks
Amazing
Excellent presentation sir tq so much
