The thoracic , or chest wall, consists of a skeletal framework, fascia, muscles, and neurovasculature – all connected together to form a strong and protective yet flexible cage. The thorax has two major openings: the superior thoracic aperture found superiorly and the inferior thoracic aperture located inferiorly. Superior Thoracic Aperture or Thoracic Outlet – The narrow opening through which chest cavity communicates with the root of the neck BOUNDARIES: Posteriorly – body of first thoracic vertebra Laterally – medial edges of first ribs and their costal cartilages Anteriorly – superior margin of manubrium sterni CONTENTS: Esophagus The thoracic cavity is a central compartment within the upper part of the torso, enclosed by the ribs, the vertebral column, and the sternum. It houses vital organs such as the heart, lungs, and major blood vessels, as well as portions of the esophagus and trachea. Location The thoracic cavity is located in the chest The thoracic cavity , also called the chest cavity , is a cavity of vertebrates bounded by the rib cage on the sides and top, and the diaphragm on the bottom. The chest cavity is bound by the thoracic vertebrae, which connect to the ribs that surround the cavity .
