Respiratory System 11, Regulation of respiration

If impulses from the brain stem stop, so does breathing. Learn about how the vital processes of breathing in and out are controlled by the brain stem.

The primary respiratory area is found in the;
a. cerebrum
b. midbrain
c. pons
d. medulla oblongata

Forced breathing out during exercise stimulates which group of muscles?
a. vastus lateralis
b. sternocleidomastoids
c. external intercostal muscles
d. internal intercostal muscles

Which neurological structure inhibits further inhalation, thereby preventing overinflating of the lungs
a. medullary ventral area
b. medullary dorsal area
c. pneumotaxic area in the pons
d. apneustic centre in the pons

Which neurological structure prolongs inhalation thereby promoting deeper breathing?
a. medullary ventral area
b. medullary dorsal area
c. pneumotaxic area in the pons
d. apneustic centre in the pons

Increased impulses from the proprioceptors during running initially stimulate which neurological structure?
a. medullary ventral area
b. medullary dorsal area
c. pneumotaxic area in the pons
d. apneustic centre in the pons

Carbon dioxide dissolved in water yields;
a. Sulphuric acid
b. Lactic acid
c. Hydrochloric acid
d. Carbonic acid.

I am a neuroanesthesiologist but let me confess I've never been so clear in my concept on resp centre than now .. thanks a ton sir .. you're a great and a clear teacher

[Armanijesus]

I like Dr matt & Dr Mike, I watch a lot of their videos but I'm glad I found you. You are the best. There is just something wonderfully clear when an experienced person explains things. You are making med school a lot easier. I really appreciate it.

Such an ingenious (programmed) system of feedbacks and responses! Why would I not believe in God after this! This must surely require (tremendous) application of a mind and a great intelligence, without doubt, to realize such an implementation.

This was a great video on the respiratory centre, I feel way more clear on it!

[reza]

Excellent presentation. Thanks God and thank you

[m.ziauddin]

Thank you so much sir. You are a great personality

[shashimoghe]

Thanks dr Campbell sir for videos and generosity to share it for the benefit of others. 13/02/2020

You broke everything down. Thank you so much sir😊👏🏼

[cannizaro]

Dr john Campbell sir pllzz make video on cardiac cycle ❤❤❤

[YOMDDLE]

Really enjoyed listening to this lecture!

[shubhpreetkaur]

Thank you so much sir ❤❤ you are amazing

[princewillugwu]

Thank you for this very lucid presentation.

I have a question.
I read in a publication that an area called the pre-Botzinger's complex is now seen as the pacemaker of the respiratory centre. The pre-Botzinger's complex is said to be one of the 4 components that make up the Ventral respiratory group of neurons in the respiratory centre. Please what's your take on this?

[peacemaker]

But pre botzinger complex which is located in ventrolateral medulla is a pacemaker for resp right?and my doubt is the apneustic center and pneumotaxic center work in normal state or activated only in intense activities?

[dr.yuvarajanpalanisamy]

Excellent sir.Simplistic explanation.
If you don't mind may i ask how much time you spend a day for reading and understanding and reproducing in excellent manner .

[suewright]

Truly fascinating Dr Campbell, very many thanks.

[hadijaber]

Hi doctor please make a video about blood supply to the bones

[YelenaIzKislovodska]

That's a wonderful share. Thank you for going in such details. I study anatomy as I am a becoming yoga teacher, from scratches I understand so many things now! If you know anything on Indian tecniques of breaking (called pranayam), there holding breath is recommended to practice. Doing pranayam one can increase some kind of capacity of lungs. Which is true on practice I can say. If in any video you could related to breathing techniques, Indian and otherwise. But from here I do get an idea how regulating breath one can affect emotions. Also, breathing technique is different during pilates, for example (forceful exhalations with the mouth), different breathing tecniques are recommended during various other exercises. I wonder If you you make a video from regulating one's breath during physical exercise perspective, thank you so much (because it is really hard to believe 'true yoga sources', as that information is often not real science. Hoping To understand from the scientific point of View, Thank you

[sajinigunasekara]

Sir, Isn't the pre botzinger complex, ( the area with rhythmic discharge and the small group of synaptically coupled pacemaker cells) responsible for rhythmic discharges ?

Thank u sir
