By the end of this section, you will be able to: List the structures that make up the respiratory …Bone is a frequent site of metastases and typically indicates a short-term prognosis in cancer patients. Once cancer has spread to the bones it can rarely be cured, but often it can still be treated to slow its growth. ... The radiation fields must be shaped to reduce exposure of sensitive structures such as lung, gut, kidney and liver.Lung parenchyma consists of the delicate, functional tissue of the lungs. This tissue is made up of two main components: alveoli and interstitium. Alveoli: Alveoli are tiny air sacs responsible for the exchange of oxygen and carbon dioxide in the lungs. These small sacs resemble clusters of grapes and play a crucial role in respiration.The ribs are the bony framework of the thoracic cavity. Generally, there are twelve pairs of ribs. Each rib articulates posteriorly with two thoracic vertebrae; by the costovertebral joint. An exception to this rule is that the first rib articulates with the first thoracic vertebra only. According to their attachment to the sternum, the ribs are classified into three groups: true, false, and ... Lung bases: No pulmonary nodules or evidence of pneumonia. Cardiac: Base of heart is within normal limits. No pericardial effusion. Liver: Normal size and contour. There is a new 2 cm hypoattenuating focus in segment 8. Gallbadder is surgically absent. Biliary: No intra or extrahepatic biliary dilation. Spleen: Unremarkable. Pancreas: Normal. The abdomen and pelvic regions are continuous with each other, making up the distal part of the trunk. Bar the brain, heart and lungs, this region contains virtually all your body organs, including those involved in the digestive, endocrine, lymphatic, urinary and reproductive systems. So, it is crucial that you cover this section thoroughly.Extracellular matrix: Fibroblasts produce collagen and other proteins that make up the ECM. This is the network of fibers that support tissues in the body, such as the skin, organs, and blood vessels. Tendons and bones: The collagen protein produced by fibroblast cells is a critical component of cartilage (found in joints and between bones), tendons, and bone.Anterior cervical lymph nodes are those nearest the front of the neck.These typically swell when you have a cold or strep throat. Posterior cervical lymph nodes are located behind the band of muscles on the side of the neck.These often swell when you have infectious mononucleosis.; Occipital lymph nodes are located at the back of the neck at the base of the skull.The chest (thoracic) cavity is the area surrounded by the thoracic vertebrae, the ribs, the sternum, and the diaphragm. The lungs are housed in the chest cavity, a space that also includes the mediastinum. (See also Overview of the Respiratory System.). The mediastinum is in the center of the chest and contains the heart, thymus, and lymph nodes, along with portions of the aorta, vena cava ...Glandular epithelium is an epithelial tissue involved in the production and release of different secretory products (e.g., sweat, saliva, mucus, digestive enzymes, hormones). It is arranged into structures known as glands, which can be a single secretory cell (e.g., goblet cells) or a group of secretory cells (e.g., salivary glands ).Interstitial lung disease can be caused by long-term exposure to hazardous materials, such as asbestos. Some types of autoimmune diseases, such as rheumatoid arthritis, also can cause interstitial lung disease. In some cases, however, the causes remain unknown. Once lung scarring occurs, it's generally irreversible.osseous tissue: [ tish´u ] a group or layer of similarly specialized cells that together perform certain special functions. adenoid tissue lymphoid tissue . adipose tissue connective tissue made of fat cells in a meshwork of areolar tissue. areolar tissue connective tissue made up largely of interlacing fibers. bony tissue osseous tissue . ...Aug 24, 2021 ... Normal human lungs have high signal, while the surrounding osseous structures and soft tissue have very low and no signal, respectively. The ...osteolysis. Mature bone cells found within lacunae of compact bone are called _____. Osteocytes. The protein and carbohydrate portion of bone matrix forms the ______ matter. organic. The calcium-phosphate salt that mineralizes bone tissue is called ______. hydroxyapatite. The layers of bony matrix arranged around the central canal of an osteon ...Feb 9, 2023 · This painless test uses X-rays to see the structure of your bone. Doctors assign you a T-score based on the results of your scan. A T-score of 0 means your bone density is equal to that of a young ... Jan 26, 2024 · Bones are composed of two types of tissue. Compact (cortical) bone is a hard outer layer that is dense, strong, and durable. It makes up around 80% of adult bone mass and forms the outer layer of ... The visualized osseous structures on chest CT which include the spine, ribs, sternum, scapula, and humerus should be examined on bone window settings (Level 600, Window 3000). Look at each one individually to see if it is fractured or contains a lytic or sclerotic lesion. The bones are reviewed on axial images, and the review is supplemented by ...The chest (thoracic) cavity is the area surrounded by the thoracic vertebrae, the ribs, the sternum, and the diaphragm. The lungs are housed in the chest cavity, a space that also includes the mediastinum Overview of Pleural and Mediastinal Disorders The pleura is a thin, transparent, two-layered membrane that covers the lungs and also lines the inside of the chest wall.The lungs are the largest organs of the respiratory tract. They are suspended within the pleural cavity of the thorax. In Figure \(\PageIndex{5}\), you can see that each of the two lungs is divided into sections. These are called lobes, and they are separated from each other by connective tissues. The right lung is larger and contains three lobes.Breath sounds are the noises produced by the structures of the lungs during breathing. Breath sounds are the noises produced by the structures of the lungs during breathing. The lu...A CT scan can show the shape and size of your spinal canal, its contents and the bone around it. It helps diagnose bone spurs, osteophytes, bone fusion and bone destruction from infection or tumor. Magnetic resonance imaging (MRI): This test uses a large magnet, radio waves and a computer to produce detailed images. It can reveal problems with ...These could also represent bone lesions (the report says opacities superimposed over osseous structures) and not necessarily a lung pathology. Therefore, an apical view of the chest has been suggested to ensure whether the opacities in your chest x-ray are a true pathology of either lungs or bones or are just artefactual.Bone, or osseous tissue, is a hard, dense connective tissue that forms most of the adult skeleton, the support structure of the body.In the areas of the skeleton where bones move (for example, the ribcage and joints), cartilage, a semi-rigid form of connective tissue, provides flexibility and smooth surfaces for movement.The skeletal system is the body system composed of bones and cartilage ...

Right hemidiaphragm elevation is a condition where the right side of the diaphragm, the muscle that separates the chest cavity from the abdominal cavity, is positioned higher than usual. This can affect the functioning of the diaphragm and, in turn, impact breathing and overall health.Tutorial Introduction. Visible anatomical structures in the chest should be assessed on every chest X-ray. Each of these anatomical structures should be viewed using a systematic approach. There are also important structures that are obscured or become visible only when abnormal. This tutorial describes the important anatomical structures ...The respiratory tract conveys air from the mouth and nose to the lungs, where oxygen and carbon dioxide are exchanged between the alveoli and the capillaries. Sagittal view of the human nasal cavity. The human gas-exchanging organ, the lung, is located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage.The nasal cavities are separated from each other by what structure? Maintains shape and is flexible where bone is brittle. Imp for keeping breathing passages open but is capable of breathing. The nasal cartilage are made of hyaline cartilage. What functional adaptation does cartilage have over bone in making up the external framework of the nose.Whenever you review a chest x-ray, always use a systematic approach. We use an inside-out approach from central to peripheral. First the heart figure is evaluated, followed by mediastinum and hili. Subsequently the lungs, lungborders and finally the chest wall and abdomen are examined.
