What is the thoracic wall?
Holy wall, sometimes called the thoracic wall, is the edge of the thoracic cavity, the space bounded by the spine and the chest basket that contains heart, lung, trachea and upper esophagus. This term is often used in relation to the muscles of this area itself, which includes intercostal muscles in the front of the chest, pectoralis muscles on the outside of the thoracic basket, and sometimes the membrane muscle is formed by the lower limit of the thoracic cavity. However, the hip wall may also apply to the bones of the thoracic cage or the collective layers of the skin, fat, muscle, connective tissue and bones found in the thoracic wall.
In anatomy, the torso is divided into three cavities: thoracic cavity, abdominal cavity and pelvic cavity. The pelvic cavity is the lowest of them and contains pelvic bones and are found reproductive and urinary organs and the lower end of the digestive tract. At the top is the abdominal cavity, which is located between the pelvis and the rib cage and contains lower esophage, stomach, liver, gallbladder, spleen, pancreas, intestines and kidneys.
The closed chest bin is the thoracic cavity that is bounded by the thoracic cage. It consists of the back of the back, ribs around and at the top and thoracic bones or breasts in front. The formation of the lower limit of the cavity is a membrane, a leaf of muscle stretching over the undulating basket, which is convex as the floor of the thoracic cavity and concave as the ceiling of the abdominal cavity.
between and the superficial for the bones of the thoracic cage, which protects the most important organs of the body, the muscles of the thoracic wall. The intercostals take place between the individual ribs and are arranged in several layers on both sides of the chest. The inner intercostals are the deepest and the angle down and the back of the around thoracic front back, while the outer intercostals angle down and forward. Other muscles found in the thoracic basket in the thoracic wall are the innermost intercostals, a smaller, deeper group of internal intercostals, which can be divided into transversus torracis and subcostalis muscles. In summary these muscles of the rib cage eitherThey stretch the ribs, expand the rib cage to allow the lung inhalation, or attract them together to collapse the chest basket during exhalation.
The membrane muscle below and the pectorals on the outside of the rib cage can also be calculated between the muscles of the thoracic wall. It behaves almost like an suction cup and the membrane attracts air into the lungs as it is downloaded by creating a vacuum in the thoracic cavity. Pectorates move the arms inside the shoulder joint and press the shoulders as a unit. They do not move the rib cage directly, so they tend to be excluded from the muscles of the thoracic wall, but their location in the chest on both sides of the chest sometimes allows them to calculate between the structures of the thoracic wall. Similarly, other structures in the wall of the chest on the outside of the rib cage, such as fascia or connective tissue between these muscles and bones, oily tissues of the thoracic wall and skin, may be included.
