A, the composition of the ribs:
Ribs are long bones, which are divided into head, neck and body. The head is connected to the sternum, the neck is connected to the ribs, and the body is connected to the thoracic vertebra in front. Ribs vary in shape and size, and the first to seventh ribs are thicker, which is called true ribs. The eighth to twelfth ribs are called false ribs, and the eighth to tenth ribs are similar in shape to real ribs, but smaller than real ribs.
Intercostal muscle is a muscle that connects two adjacent ribs and is located between them. These muscles help the ribs move and keep the chest stable. Intercostal nerve is a nerve originating from the spinal cord, which is distributed between ribs and provides sensory and motor functions for the chest. Intercostal blood vessels provide blood supply to ribs and their surrounding tissues.
Second, the role of ribs:
The main functions of ribs include supporting the chest structure, protecting the organs and tissues of the chest, participating in breathing exercises and helping to maintain body posture. In the process of breathing, the movement of ribs changes the chest volume, thus realizing the breathing function.
Three, rib injury and treatment:
Chest trauma can easily damage ribs. Fracture may lead to pain, dyspnea, lung infection and other complications. The treatment of rib fracture includes conservative treatment (such as rest and painkillers) and surgical treatment (such as internal fixation or external fixation).
Fourth, the relationship between ribs and diseases:
Abnormal growth or dysplasia of ribs may lead to skeletal diseases such as rickets and rickets. These diseases will affect the normal development and function of bones and need to be diagnosed and treated in time.
Clinical application of verb (abbreviation of verb) rib;
In surgery, ribs are one of the commonly used surgical methods. By cutting the ribs, doctors can enter the chest cavity for surgical operations, such as heart surgery and lung resection. In addition, ribs are also diagnostic signs of some diseases.
Sixth, the importance of protecting ribs:
Because ribs provide support and protection for the chest, protecting ribs is very important for keeping healthy. Pay attention to correct posture in life, avoid trauma, strengthen exercise and reduce the risk of rib injury.
