The thoracodorsal artery is a branch of the subscapular artery. It passes inferior-ward upon the surface of the serratus anterior muscle (which it supplies posteroinferiorly to the lateral thoracic artery). [1] It is accompanied by the thoracodorsal nerve along its source. It also supplies the latissimus dorsi. [citation needed]
The intercostal arteries are a group of arteries passing within an intercostal space (the space between two adjacent ribs). There are 9 anterior and 11 posterior intercostal arteries on each side of the body. The anterior intercostal arteries are branches of the internal thoracic artery and its terminal branch – the musculophrenic artery.
In reference to the muscles of the thoracic wall, the intercostal nerves and vessels run posterior to the internal intercostal muscles: therefore, they are generally covered on the inside by the parietal pleura, except when they are covered by the innermost intercostal muscles, innermost intercostal membrane, subcostal muscles or the transversus thoracis muscle.
A thoracostomy is a small incision of the chest wall, [1] with maintenance of the opening for drainage. [2] It is most commonly used for the treatment of a pneumothorax.This is performed by physicians, paramedics, and nurses usually via needle thoracostomy or an incision into the chest wall with the insertion of a thoracostomy tube (chest tube) or with a hemostat and the provider's finger ...
The internal thoracic artery (ITA), also known as the internal mammary artery, is an artery that supplies the anterior chest wall and the breasts. [1] It is a paired artery, with one running along each side of the sternum , to continue after its bifurcation as the superior epigastric and musculophrenic arteries .
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 ...
structures of the cardiovascular system, including the heart and great vessels, which include the thoracic aorta, the pulmonary artery and all its branches, the superior and inferior vena cava, the pulmonary veins, and the azygos vein; structures of the respiratory system, including the diaphragm, trachea, bronchi and lungs [1]
The intercostal muscles comprise many different groups of muscles that run between the ribs, and help form and move the chest wall. The intercostal muscles are mainly involved in the mechanical aspect of breathing by helping expand and shrink the size of the chest cavity. [1]
