What are the outer internet muscles?
The outer internet muscles are a type of muscle found between the ribs in the human chest. They primarily help in inhalation during breathing by moving ribs up and creating space in the lungs. Each of the 11 external intercostal muscles is close to the corresponding internal intercostal muscle and intercostal nerves.
intercostal spaces - or gaps between each of the ribs - contain external internet muscles. Structurally, one rib starts on the back of the bottom of the bottom and extends forward and the upper part of the rib at the bottom. Then they become thin tissues called the front intercostal membrane near the ribs' inner cartilage in the skin. The fibers of the skin and connective tissues known as the fascia cover these muscles.
The diagonal slopes in the muscles allow easier contraction and the ability to close the withdrawal an important part of the function of the external intercostal muscles. Like any outer internet muscular Contracts, it shortens and thus increases the two ribs to which it is attached. OnceThe ribs move upwards, increasing the amount of space inside the lungs.
External intercostal contractions begin in response to contractions in the muscle at the bottom of the cage of the rib or membrane. This, in turn, causes the externus to extend the abdominal walls - to expand. The whole process reduces the chest pressure and allows incoming air to fill the lungs, inciting the inhalation process.
intercostal muscles also include internal intercostal muscles. While some of these specific types of muscles also perform inhalation processes, most of the inner muscles help in exhalation. They are perpendicular to the outer internet muscles. Together, both types of inter -stand muscles work to regulate the respiratory processes that maintain organisms.
nerves that provide motor functions pass through inter -stands. The main intercostal nerve is placed around the internal internet muscle. One branch of nerve jDE between external and internal inter -stands and provides nerve function to the first. This branch is usually called an external intercostal nerve. Another branch of the main nerve runs near the external intercostal muscles and helps with nervous functioning in the abdominal muscles.
If these muscles are torn or otherwise damaged, breathing may be painful. Sharp pain after inhalation is not unusual for inter -house injury. Usually such injuries arise from recurring movements that turned the fuselage or swinging arms. Stretching and respiratory exercises before strenuous activity can help reduce the risk of injury.
