The raphe can grow inward.
The direction of growth of the raphe is roughly parallel to that of the human sternum, and growth inward into the chest cavity is abnormal. The raphe is a cartilaginous tissue, the back of which is smooth. Generally, inward growth does not lead to damage to internal organs or affect their function, and if there is no discomfort it usually does not require special treatment.
It is located at the lowermost end of the sternal body, the upper end of the raphe is connected to the sternal body, and the lower end is free, usually about flat to the level of the ninth thoracic vertebra. Because the sternum resembles a downward-facing sword, the lower end of the sternum is a thin, irregularly shaped piece of bone called the raphe.
The xiphoid process protects the heart at the anterior and inferior end of the chest wall in the heart region.
If the raphe grows inward, you should go to the regular hospital in time, complete the relevant examination, and the doctor will give the correct treatment according to the specific situation, so as not to delay the condition.
