The bony skeletal part of the thoracic wall is the rib cage, and the rest is made up of muscle, skin, and fasciae.. The chest wall has 10 layers, namely (from superficial to deep) skin (epidermis and dermis), superficial fascia, deep fascia and the invested extrinsic muscles (from the upper limbs), intrinsic muscles associated with the ribs (three layers of intercostal muscles), endothoracic ...
The thorax (pl.: thoraces or thoraxes) [1] or chest is a part of the anatomy of mammals and other tetrapod animals located between the neck and the abdomen. [ 2 ] [ 3 ] In insects , crustaceans , and the extinct trilobites , the thorax is one of the three main divisions of the body, each in turn composed of multiple segments.
The thoracic cavity (or chest cavity) is the chamber of the body of vertebrates that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). The central compartment of the thoracic cavity is the mediastinum.
CT thorax (axial, mediastinal window) The mediastinum lies within the thorax and is enclosed on the right and left by pleurae. It is surrounded by the chest wall in front, the lungs to the sides and the spine at the back. It extends from the sternum in front to the vertebral column behind. [3] [4] It contains all the organs of the thorax except ...
The parasternal line is a vertical line on the front of the thorax. It is midway between the lateral sternal line and the mid-clavicular line. External links
The portion of the pleura seen as the outer layer covers the chest wall, the diaphragm and the mediastinum and is often also misleadingly called the parietal pleura. A correct anatomical nomenclature refrains from using the ambiguous terms visceral and parietal in favour of a 4-portion system based on the structures the pleura covers: pulmonary ...
3D rendering of a high-resolution CT scan of the thorax. The anterior thoracic wall, the airways and the pulmonary vessels anterior to the root of the lung have been digitally removed in order to visualise the different levels of the pulmonary circulation. The lungs have a dual blood supply provided by a bronchial and a pulmonary circulation. [4]
Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
