This illustration reflects the right mediastinum of the human chest wall.  The word “neglected” was chosen because this particular cavity is underutilized by many because of the lateralization issues that exist in our body.  Truthfully, the mechanics that drive this cavity’s function begin on the contralateral side.  Without good apposition on the left side of the rib cage generation of diaphragmatic influence opposition to the lobes on the right side is diminished.  Therefore, the underutilized activity on the right side results in not only biomechanical issues to the upper quadrant on the right side but also does not allow this quadrant to be fully utilized as it should be.
