Study without missing a single muscle
There are muscles in our body that can move according to our own thoughts, and there are muscles that cannot move as we wish. In medical terms, muscles that can move freely are called ‘voluntary muscles’, and muscles that cannot move as desired are called ‘involuntary muscles’.
Arms, legs, fingers, toes, back, neck, etc. can move whenever I want to, but there are muscles that move on their own, completely unrelated to my thoughts. These muscles are called 'involuntary muscles' or 'smooth muscles'. That is, blood vessels, large intestine, small intestine, duodenum, rectum, stomach, etc. These smooth muscles are hormonally driven.
For example, when food enters the body, hormones are released to move the stomach and large intestine. Therefore, if the hormones that move these smooth muscles are not secreted properly, the function of the organs will deteriorate. In my own experience, when I'm stressed, I feel that organ function slows down and blood vessels constrict. The stress hormone that makes this possible to block hormones is called the hormone noradrenaline.
However, there is a smooth muscle that practitioners should be aware of. It is a smooth muscle associated with the lungs. Doctors say there are no muscles in the lungs. So what is the smooth muscle of the lungs I'm talking about?
First, let's check the breathing passage. Air enters through the nose, passes through the nostrils, passes through the paranasal sinuses, enters the trachea, passes through the larynx, and passes into the primary bronchi. From the primary bronchus, it passes through the secondary bronchus, which separates into both lungs, and passes through the 3rd, 4th, 5th, and 6th bronchi, which gradually extend like branches of a tree. And finally, in the alveoli, it gets into the blood. In this way, the bronchi gradually narrow as they go from the throat to the lungs, and the muscles of this bronchus are called smooth muscles.
It is common sense that when you are stressed, the smooth muscle in this bronchial tube contracts, preventing oxygen from entering properly. So what can we do to make these smooth muscles function smoothly without contraction? You shouldn't be stressed right away. However, it is a pity that our lives cannot live without stress. Please keep in mind that practitioners must keep their minds well-controlled so as not to stiffen these smooth muscles.
