chest breathing and belly breathing and normal breathing
Hello:
I am very confused here.
when a human breathes he use both intercostal muscles and Diaphragm muscle to change the volume of the lungs and this happens with help of the medulla ( andningscentrum).
but the book states that we use either belly breathing ( that only uses Diaphragm muscle) or chest breathing ( that only uses intercostal muscles) .... is that wrong because the breathing mechanism uses both intercostal muscles and Diaphragm muscle at the same time?????
one more thing I understand breathing with help of the autonomic nervous system which means that intercostal muscles and Diaphragm muscle is controlled (involuntary) by the breathing center that sends its signal by the autonomic nervous system. Is that right???
if that is right... how can we stop Diaphragm muscles from moving while breathing as chest breathing ... and we can stop intercostal muscles from moving while breathing as belly breathing???
Okay, I understand that both intercostal muscles and Diaphragm muscles are skeletal muscles which means they can be controlled voluntarily by CNS using the somatic nervous system. but can the somatic nervous system overlord the autonomic nervous system????
How many types of breathing are there ??? is it three or two mechanisms???
Here is link for what I am talking about :https://www.youtube.com/watch?v=GqkMzds77f8
Thanks

Have a look at e.g. this page, which describes how breathing is performed in the body:
