Sep 19, 2023 · 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.

The thoracic wall or chest wall is the boundary of the thoracic cavity. The bony skeletal part of the thoracic wall is the rib cage, and the rest is made up of muscle, skin, and fasciae.

Jul 30, 2023 · The thoracic wall is bounded anteriorly by the sternum and costal cartilages; laterally by the ribs and intercostal spaces; posteriorly by the thoracic vertebrae and intervertebral discs; superiorly by the suprapleural membrane and inferiorly by the respiratory diaphragm.

Jun 13, 2016 · From the midclavicular line and around the thoracic wall to the vertebral column, the inferior margin of the lung can be approximated by a line running between rib VI, rib VIII, and vertebra TX. The inferior margin of the pleural cavity at the same points is …

Jul 30, 2023 · The thorax is the region between the abdomen inferiorly and the root of the neck superiorly.[1][2] The thorax forms from the thoracic wall, its superficial structures (breast, muscles, and skin), and the thoracic cavity.

Jul 10, 2016 · The inferior aperture of the thorax is formed by the lower margin of the ribs and costal cartilages and is closed off from the abdomen by the respiratory diaphragm (Fig. 4.1).

Jun 16, 2016 · The inferior thoracic aperture (the anatomical thoracic outlet) conveys the inferior vena cava (IVC), aorta, esophagus, nerves, and thoracic lymphatic duct between the thorax and the abdominal cavity.

Inferiorly, the diaphragm forms the physical boundary between the thoracic cavity and the abdominal cavity. The thoracic cavity contains a small opening on its superior end called the superior thoracic aperture and a relatively large opening on the inferior end called the inferior thoracic aperture.

Jun 13, 2016 · The superior thoracic aperture is open, allowing continuity with the neck; the inferior thoracic aperture is closed by the diaphragm. Fig. 3.1 Thoracic wall and cavity. The musculoskeletal wall of the thorax is flexible and consists of segmentally arranged vertebrae, ribs, and muscles and the sternum.

Mar 16, 2021 · The thoracic (chest) wall is composed of the rib cage, inner and outer muscles, vessels, lymphatics, fascia, and skin. The rib cage is formed by the ribs, costal cartilages, sternum, and thoracic vertebrae.
