The Posterior Mediastinum In this article, we shall look at the anatomy of the posterior mediastinum – its borders, contents and clinical correlations. Borders The posterior mediastinum is bordered by the following thoracic structures: 1  Lateral: Mediastinal pleura (part of the parietal pleural membrane). 2  Anterior: Pericardium. 3  Posterior: T5-T12 vertebrae. 4  Roof: Imaginary line extending between the sternal angle (the angle formed by the junction of the sternal body and manubrium) and the T4 vertebrae.

Editorâs Choice Thorax is one of the world's leading respiratory medicine journals, publishing clinical and experimental research articles on respiratory medicine, paediatrics, immunology, pharmacology, pathology, and surgery. Thorax seeks to publish significant advances in scientific understanding, which are likely to impact on clinical practice. This includes articles concerning basic and translational mechanisms with application to clinical material (cell and molecular biology, genetics, epidemiology, and immunology).

- Wrong... the bone thorax protects the heart and LUNGS as it also allows the respiratory muscle to create a vacuum that will draw… air into the lungs. while the Ribs withing in the bone thorax will protect not only the thoracic organs, but as well the spleen, most of the liver and to some extent the kidneys.

The Thoracic Cage The thoracic cage (rib cage) forms the thorax (chest) portion of the body. It consists of the 12 pairs of ribs with their costal cartilages and the sternum ([link]).

Rib cage For the individual bones, see Rib. For ribs of animals as food, see Ribs (food). For other uses, see Rib (disambiguation). The rib cage is an arrangement of bones in the thorax of all vertebrates except the lamprey and the frog. It is formed by the vertebral column, ribs, and sternum and encloses the heart and lungs. In humans, the rib cage, also known as the thoracic cage, is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the pectoral girdle (shoulder girdle), forming a core portion of the human skeleton.

- In summary, each pleural cavity is defined by a space surrounding each lung and lined by a pleural membrane. Each pleural cavity is lined by a pleural membrane that is composed of two layers. The visceral pleura surrounds the outside of the lung.The parietal pleura lines the inside of the chest wall and extends over the diaphragm.These membranes secrete a lubricating fluid, which allows for free movement of the lungs against the chest wall when we breathe.he visceral pleura surrounds the outside of the lung.

Chest Wall Anatomy The anterior border includes the pectoralis muscles, and the posterior border includes the latissimus dorsi, which are both visible at the skin surface as the anterior and posterior axillary folds, respectively.The anterior axillary line is drawn along the anterior axillary fold and followed down the chest wall.

thorax the part of the body between the neck and abdomen; the chest. It is separated from the abdomen by the diaphragm. The walls of the thorax are formed by pairs of ribs, attached to the sides of the spine and curving toward the sternum.

- These three portions of the sternum arise as separate bones and may fuse partially or completely with one another. The sternum articulates (makes contact) with the cartilages of the first seven ribs and the clavicles (the collar bones) to form the middle portion of the anterior front wall of the thorax.

Mediastinum 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, and contains all the organs of the thorax except the lungs. It is continuous with the loose connective tissue of the neck.

- The sternum is located in the middle of the thorax, in between the two sets of ribs. 1  Early on during development, the sternum is divided into 3 regions, each known as sternebra. 2  The average length of the sternum is approximately 17 cm. 3  The sternum connects to the ribs via cartilage.

Mediastinum Structure [edit]. 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, and contains all the organs of the thorax except the lungs.It is continuous with the loose connective tissue of the neck. This lower part is subdivided into three regions, all relative to the pericardium-the anterior mediasteinum being in front of the pericardium, the middle mediastinum contains the pericardium and its contents, and the posterior mediastinum being behind the pericardium.

Lungs 1 Hilum: At about the middle of the mediastinal surface, there is a depression where the bronchi, blood vessels and nerves, which form the root, enter of leave the lung. 2  Anterior border: The anterior border of the lungs is thin and overlaps the heart.3  It is here on theleft lung that the cardiac notch is found.hape of lungs: Each lung is conical in outline and is covered with visceral pleura. It suspends freely in its own pleural cavity and is attached to the mediastinum only through its root (the place where blood vessels and bronchi attach to the lung at hilum).

Thorax (insect anatomy) Thorax (insect anatomy) The thorax is the midsection (tagma) of the insect body. It holds the head, legs, wings and abdomen. It is also called mesosoma in other arthropods. It is formed by the prothorax, mesothorax and metathorax and comprises the scutellum; the cervix, a membrane that separates the head from the thorax; and the pleuron, a lateral sclerite of the thorax.

Thoracic Wall, Intercostal Space the opening at the inferior end of the rib cage through which thoracic structures exit the thorax; it is bounded by the T12 vertebral body, both 12th ribs, the costal cartilages of ribs 7-12, and the xiphisternal joint.

The Pleurae and Pleural Cavities 1 The parietal pleura is also attached to the pericardium. 2  The parietal pleura is given different names according to the parts with which it is associated: costal pleura (ribs and sternum); mediastinal pleura (mediastinum); diaphragmatic pleura (diaphragm); and pleural cupula (apex of the lung). A pleural sac surrounds each lung. 2  A parietal layer of pleura forms its external wall and a visceral layer the internal wall that invests the lungs. 3  The pleura cavity is a separate and closed potential space.

Parietal pleura The costal segment of the parietal pleura acts as a lining for the inner slope of the ribs and intercostal muscles located within them. It is the endothoracic fascia that separates it from these structures. The intercostal nerves innervated this section.arietal pleura Location. It is affixed to the wall of the thoracic cavity and covers the superior diaphragm surface. The endothoracic fascia joins it to the inner side of the thoracic cavity.

Mediastinum The mediastinum is an area found in the midline of the thorax that is surrounded by the left and right pleural sacs. It is divided into the superior and inferior mediastinum, of which the latter is larger. The inferior mediastinum is further divided into the anterior, middle and posterior mediastinum. In this article, the borders of each section of the mediastinum and their contents will be discussed.

Thorax The chest. In the human body, the region of the thorax between the neck and diaphragm in the front of the body is called the chest. The corresponding area in an animal can also be referred to as the chest. The shape of the chest does not correspond to that part of the thoracic skeleton that encloses the heart and lungs.
