The lower segment is further split into three sections, the anterior, middle and posterior mediastinum. The anterior mediastinum sits in front of the pericardium, the fluid-filled pouch that contains the heart and its major blood vessels. The middle mediastinum houses the pericardium and all of its components.The posterior mediastinum lies behind the protective pouch of the heart and runs parallel to the spine.he mediastinum is the located in the thoracic cavity, and includes the thymus gland. The posterior mediastinum protects the trachea, as well as the lungs.
