What is osseous structures in lungs.

The osseous portion refers to the third of the Eustachian tube nearest to the middle ear. It can be variably surrounded by peritubal air cells. Along the roof of the osseous part of the Eustachian tube is a canal containing the tensor tympani muscle. The distal end of the osseous portion is formed by the petrous part of the temporal bone.The lungs (plural in Latin: pulmones, singular: pulmo) are the main respiratory organs located in the thorax.

Epithelial Tissue Function: Epithelial tissues provide the body's first line of protection from physical, chemical, and biological damage. The cells of an epithelium act as gatekeepers of the body, controlling permeability by allowing selective transfer of materials across its surface. All substances that enter the body must cross an epithelium.

formed by the presence of air in structures that approximate each other, delineating the respectively thinner and thicker intervening tissue on both sides. 4 The mediastinal lines correspond to the contours of the middle and superior mediastinum and represent the edges of a dense, pleural-covered structure mar-ginated by the air within the lung.

CT scan is a type of imaging test. It uses X-ray and computer technology to make detailed pictures of the organs and structures inside your chest. These images are more detailed than regular X-rays. They can give more information about injuries or diseases of the chest organs. In a CT scan, an X-ray beam moves in a circle around your body.Density. Calcifications normally appear as mineralised densities with an attenuation coefficient higher than soft tissue but lower than bone (Fig. 2).With computed tomography (CT), there is a wide range of Hounsfield unit (HU) values for calcifications, but it is mostly between 100 and 400 HU, whereas bone reaches higher values (700 HU for trabecular bone and over 1500 HU for cortical bone ...Lung opacity progressively increases as the degree of atelectasis increases. As a lobe loses volume, structures such as the mediastinum, hilum, or hemidiaphragm shift toward the collapsed lobe. In most patients, the right hemidiaphragm is higher or at the same level as the left hemidiaphragm. With volume loss, particularly in the lower lobes ...A bronchial tree (or respiratory tree) is the collective term used for these multiple-branched bronchi. The main function of the bronchi, like other conducting zone structures, is to provide a passageway for air to move into and out of each lung. In addition, the mucous membrane traps debris and pathogens.A doctor has provided 1 answer. my doctor commented the osseous structures are remarkable for mild degenerative changes of the spine. what does that mean?: Incidental findings: The bone parts of your spine have early signs of.
