Painful Chest Muscles Anatomy
To better understand chest wall pain, it helps to understand the anatomy of the chest.
The chest includes the part of the trunk between the neck and the abdomen. The chest holds the heart and lungs, as well as the esophagus and large blood vessels that connect to the heart.
The chest wall consists of the bones, cartilage, muscles and ligaments that hold the contents of the chest. The rib cage is made up of the vertebrae, ribs and sternum.
The ribs are attached to the vertebrae in the back and the sternum in the front. Joints between the vertebrae, ribs and sternum allow the bones to move.
The chest wall is also made up of soft tissues:
