[@kariahjeter9727]

I always watch Armando's videos for anything Anatomy and Physiology related. Thank you for these incredible videos. I use these when I get bored with reading the textbook. It's a good way to break up the flow of studying. You always explain things very well and your drawings are great!

[@zakirullahkhan3506]

Ya great videos

[@mabvutobanda1075]

We are the same

Same here

[@AminaYasin-x7b]

Yes really

[@nmarvlonam9908]

I'm a first year medical student, and i want to thank you for the educational videos. They are really helpful

[@jory1430galaxy]

where are you now?

[@georgeskazadi]

probably third year

[@hardz2110]

probably tired in bed

[@novachrono2236]

probably got eliminated during his first year lol

[@novachrono2236]

its where they usually quit medicine lol

[@fifa08ronaldhino]

Thank you so much for summarising my 1 hour lecture into a quick and enjoyable 8 minutes, do post more videos!

[@amulyamaddineni4383]

This vedio is brief and to the point. Love how he dint drag any topic or make it boring. The diagrams are amazing too. Thank u soo much

[@donnafp7559]

Just reviewing this and I'm being taught just the opposite for the VRG and the DRG. My book and professor state the VRG is quiet breathing, and only active during exercise, whereas the DRG controls the basic rhythm of breathing by triggering inspiratory muscles via the phrenic nerve and receives sensory information via chemo and mechanoreceptors.

[@jitendrasingoriya515]

Donna Foster Paulsen i totally agree

[@MiniBlob75]

To quote from my phys textbook: "The most common early explanation for generation of the respiratory rhythm (e.g., that proposed by Lumsden; see p. 702) is that no individual region of the DRG or VRG is sufficient to generate the rhythm but that many of them are necessary. A normal rhythm would require the component neurons in multiple brainstem regions to be “wired up” in a specific way." (Boron & Boulpaep 3rd ed). They also bring up other newer theories such as it would be in preBötC or a distributed ocillator model, but stresses that no model is today universally accepted.

[@shobhitlitoriya5275]

Same here😢😢

[@myowntwofeet]

Same, The DRG is "appears to be the pacesetting respiratory center" and the VRG is involved in forced inspiration and expiration.

[@hanuaggarwal536]

Dafuk me too...😌😌

[@JohnCitizenCitizen]

thanks armando, it can't be easy to make these videos but you're helping so many people

[@lucejuice33962]

amen to this!

[@Campbellteaching]

I think its the dorsal group of neurons that generate rhythmicity, you say it is the ventral group? I think the rhythm comes from the inspiratory respiratory centre, not the expiratory centre.

[@xpressionswithqueenb2670]

Dr. John Campbell exactly!!

[@hemantmodi1032]

maybe he is talking about pre-botzinger complex..

[@Marikrie]

that is exactly what I thought!

[@SROY28]

The Pre-Botzinger complex and the Botzinger complex are both parts of the ventral respiratory group of neurons. The Pre-Botzinger controls the rhythm, the Botzinger complex stops the inspiration.

[@BashiirCabdi-g2f]

@@hemantmodi1032even pre botzinger has dorsal

[@sharontalana2897]

I slayed the paper today because of your videos..

[@nothingspecial1415]

how can i thank you enough sir Armando? you're videos are of great help. i usually watch these whenever i get bored reading books or before i start reading them. kudos! i hope you'll continue producing such videos as this. you can help hundreds if not thousands of medical students in their studies. 😊 God bless po!

[@sarasultana9804]

The explanation was really very clear and I understood it really well. Thanks for it. Another thing that I noticed is that you actually drew all of this by hand on a paper. I mean that takes a lot of effort to first be so clear in the concept yourself and make sure that you don't go wrong anywhere. Hats off to you!!

[@ansaritasmiyamohammedsalah6140]

Your videos are helping us so much I don't know how to thank you for your work. You are awesome ❤

Because of you i scored 82/100 marks in Physiology theory and 80/100 marks in physiology practical and oral viva...! Bravoooo

[@dr.ahmedelmekaty6479]

please keep uploading new video in medicine field your videos are amazing and easy to understand , you are the best channel for medine on youtube i will tell all my classmate about you , i think you are the reason i will graduate this year ,cheers

[@paddymcdougle]

Definitely going to watch this when I have the time. Good to see more videos.

[@krishnapriyamohandas7382]

I am addicted to your videos.I am addicted to biology now.Thanks to you sir.☺

[@Anyone_100]

YOUR 40MIN VIDEOS = MY TEACHER'S 5day 1hr LECTURE

[@hussainnma625]

Inspiration muscles = diaphragm + external intercostal muscles these two during quite breathing but during forced inspiration the accessory muscle ( sternocleidomastoid and scaleni) will contract Expiration muscles = on muscle action during quite breathing but in forced expiration the ( abdominal muscles + internal intercostal muscles) will contract

[@hussainnma625]

" No muscle action during quite breathing in expiration "

[@peterphan6211]

I think we dont need muscle action in the normal expiratory. However, in the forced expiration, some muscles (such as the abdominal m. and the internal intercostal m.) need to be used to help push the air out of the lung (especially when we do heavy exercises and need more oxygen)

[@johnorta8408]

Expiration is passive my friend.

[@lujainhisham1283]

Thank you for helping me to study for anatomy, biochemistry and physiology

[@kazzooghalian4309]

Appreciate ur video dude, I have my physiology exam tomorrow and u helped clear up a lot stuff

[@gabrielasomaning9905]

from GHANA WEST AFRICA , ARMANDO U ARE A GREAT TEACHER

[@mariemendez-nunez912]

Thank you for another wonderful video. For visual learners, you are a real blessing!

[@livelaughlove6952]

great video thank you. quick question in med school we learned that caffeine can help stimulate the respiratory center by acting as an adenosine antagonist. just wondering if you might be able to expand on that in this topic in a future video? thank you for all your help!

[@givemeaname6625]

This man is making my life easier 😭 angel in disguise

[@akanksha786]

[@cikookie]

Thank you , Armando. Your video has been so helpful for me .

[@zubairali8912]

Very nice every thing becomes clear, nice explanation with graphs and figures , drawing

[@VyvienneEaux]

You know what I can't find anywhere? The mechanism of H+ control of the respiratory center. Do the peripheral H+ cause depolarization of the chemoreceptors, which induce an excitatory PSP in the pontine respiratory centers thus bringing these centers closer to threshold (and medullary chemoR-> medullary resp. center)? If you know, I would greatly appreciate a response.

[@fadumomohamed6822]

b) Where is the respiratory control centre located? What is the stimulus that causes the respiratory control centre to increase respiratory rate? Of the three, which is the primary stimulus

[@Marina-jw4sg]

Thankyou so much this summarised my 2 hour long lec in 7 mins!

[@dranze2020]

what is apneustic and pneumotaxic centres. I remember hearing these terms .. the above video is superb.. it reduces learning time of 1 HR to under 10 minutes

[@pawesome1458]

I loved the video! I know a lot of hardwork goes behind this 8 minute video. Great work sir! You cleared all my concepts. thank you sir :)

[@muhieddineitani]

Can you please upload the picture?

[@39-manuskumar92]

Your diagrams are genius ,awesome.thankyou

[@hassaanrathore]

Interesting. SO the VRG determines the rhythmicity and not DRG as written by Guyton ?

[@polightningmcneil3144]

I'm an Inventor, Delbert Mc Neil, and the reason that you are getting my support, because your equation on the "Control of Respiration" has a "Lung Power Formula" and I've invented a working prototype a " Respiratory Training Breathing Cycle" that scientifically proves your equation contributes to the vital organs reparative ability, and strengthening the heart and lungs; in addition, that equation dose addresses and solves obesity problems and many health issues...under the technique "Lung Power Performance" ...if you would like to experience how and the benefits of your equation...befriend me on face-B...

[@TheGustavohadaya]

Woud it not be Hering-breuer reflex instead hering-brever??

[@LauraRojas-gx9sg]

Why does he draw some lines significantly thicker? Is is because the majority of the O2/CO2 is transported that way? sorry for my dumb question

[@E75-w9v]

finally somewhere that explains the difference in the dorsal and ventral!!!!

[@ahsenaftab6220]

+Muhammad Hussain Hosiny. thanks bro

[@venkateshanantharaman6773]

Ventral plays role in both expiration and inspiration.When the respiratory drive for increased pulmonary ventilation becomes greater than normal, respiratory signals spill over into the ventral respiratory neurons from the basic oscillating mechanism of the dorsal respiratory area. As a consequence, the ventral respiratory area contributes extra respiratory drive as well. Whereas the dorsal region place a role in rhythmicity. I think Armando inverted it.

[@cowboyzcrazy21]

Great video. However at the 34th second you state that the ventral group controls rhythmic breathing, but BRS Phys states that it's the dorsal group that controls rhythmic breathing.

[@amylavin7538]

You are amazing! Thank you for all of your helpful videos.

[@chviswanath]

Amazing ❤

[@ahmedhosny266]

I have a question, is central chemoreceptor affected by pH?

[@lilly1954]

You are really talented! Thank you so much!

[@nurtikaafiw5963]

so peripheral chemoreceptor is stimulate the neuron in pons or in medulla (right after from aortic and carotid body) ?

[@karanjoshi6033]

Are the carotid and aortic bodies affected by PO2 only or even HbO2 is factored in?

[@DJM3KS]

The dorsal is responsible for the rythmicity of the breathing NOT the ventral

Superb as always, thanks.

[@rajajha3057]

I have a doubt about VRG (ventral respiratory centre? )how it is help in rhytmicity of respiration ? according to me a nucleus of pre-botzinger complex present in medulla and it help in rhtymicity of respiration ? m i right or wrong plez tell me ?

[@luciamontes3572]

Thank you so much . This video was so helpful !

[@brassicacampestris1410]

Can we call Afferent and efferent nerves of respiratory center as Dorsal and ventral respiratory groups

[@brassicacampestris1410]

My teacher gave me assignment of difference between afferent and efferent nerves of respiratory centers so can I write something about dorsal and ventral respiratory group

[@nainyarora6789]

you're amazing!!! Thank you for making everything so easy! :)
