The anterior upper chest area (Regio thoracis superior) is the most protruding area of the chest of the anterolateral wall. It is located above the upper edge of one of the lower costal arches, bounded above by the clavicle. The top is adjacent to the neck area. The line of the collarbone runs in front. Below, this area forms a protrusion under the front surface of the arm; it connects the chest to the shoulder.
The Front Upper Chest area has several important functions:
1. Respiratory - The main function of the chest is to perform the respiratory function. The front portion of the breastbone supports and strengthens the rib cage, creates space for the lungs and helps air circulate in the area. The posterior upper region of the chest is also involved in breathing. 2. Protective - The upper front breast serves to protect the heart and lungs from external injury. This area contains the pectoral shield, made up of muscles and ligaments, which protects these organs from impacts and other damage.
