Specializes in Internal Medicine. Lung densities: When we physicians get a report like this we sit down with the radiologist and get a differential diagnosis, ask what other studies (?ct scan) would be helpful or what consultants (such as a pulmonologist) he/she would recommend. Tuberculosis, active or dormant often affects the upper lobes.The heart is located in the middle mediastinum. Other visible structures of the mediastinum should also be checked when viewing a chest X-ray. These include the aortic knuckle, descending aorta, aortopulmonary window, and right paratracheal stripe. Some structures of the mediastinum are not visible on a chest X-ray, for example the oesophagus ...Tissue that gives strength and structure to bones.

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 ...Bones: Osseous structures refer to bony structures such as the skull, spine and bones of the limbs. I suspect what you are seeing is a typo. It is common for radiology reports to read "osseous structures are unremarkable". Please confirm with the Radiologist that interpreted the exam.Spinal metastasis is common in patients with cancer. The spine is the third most common site for cancer cells to metastasize, following the lung and the liver. This amounts to 70% of all osseous metastases. Approximately 5-30% of patients with systemic cancer will have spinal metastasis; some studies have estimated that 30-70% of patients ...

Airways can be divided into upper and lower. The upper and most of the lower airways are involved in the humidification of air during breathing and its conduction to the alveoli where oxygen exchange with the blood takes place. 3. Both the upper and lower airways create dead space .

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.

Gross Anatomy of Bones. A long bone has two main regions: the diaphysis and the epiphysis ( Figure 6.3.1). The diaphysis is the hollow, tubular shaft that runs between the proximal and distal ends of the bone. Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult.Degenerative lung disease includes diffuse hypertrophic emphysema, bullous emphysema, and "vanishing" or "cotton-candy" lung. It is the author's concept that all of the above clinical entities are stages of one disease with a common etiological factor, namely obliterative vascular disease of both the bronchial and pulmonary systems.Pulmonary edema. The function of the alveoli also depends on the sacs being inflated the right amount. Some conditions and injuries can cause overdistention or surfactant dysfunction, which cause the alveoli to collapse. This makes it harder for the lungs to work. Overdistention is overstretching of the alveoli.5.3: Bone Structure. Bone tissue (osseous tissue) differs greatly from other tissues in the body. Bone is hard and many of its functions depend on that characteristic hardness. Later discussions in this chapter will show that bone is also dynamic in that its shape adjusts to accommodate stresses.From then on, lung function progressively declines with increasing age as a consequence of structural and physiological changes to the lung . We can broadly divide the structural changes of the ageing lung into three categories: changes in lung structure, changes in the chest wall and changes in respiratory muscles . The changes in the ...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.

The diaphragm is a musculotendinous structure with a peripheral attachment to a number of bony structures. It is attached anteriorly to the xiphoid process and costal margin, laterally to the 11th and 12th ribs, and posteriorly to the lumbar vertebrae.The posterior attachment to the vertebrae is by tendinous bands called the medial and lateral arcuate ligaments.What functional adaptation does cartilage have over bone in making up the external framework of the nose?, The nasal fossae are separated from each other by what structure? and more. ... What small structure in the lung is the site of the exchange of oxygen with the blood capillaries? alveoli. The surface area of the lungs in humans is about ...The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.

The rib cage, also known as the thoracic cage, is the bony structure that shapes and protects the thoracic cavity and the organs in it. It has a conical shape and looks somewhat like a birdcage (hence the name). This part of the axial skeleton is located in the chest, above the abdominal cavity. R i b C a g e.

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.Degenerative lung disease includes diffuse hypertrophic emphysema, bullous emphysema, and "vanishing" or "cotton-candy" lung. It is the author's concept that all of the above clinical entities are stages of one disease with a common etiological factor, namely obliterative vascular disease of both the bronchial and pulmonary systems.Etymology. The word thorax comes from the Greek θώραξ thorax "breastplate, cuirass, corslet" via Latin: thorax.. Human thorax Structure. In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spine, and shoulder girdle.Key points. Soft tissue abnormalities are often overlooked. Soft tissues may be mistaken for lung pathology. Smooth black lines in the soft tissue may represent normal fat - but irregular black areas may represent surgical emphysema. It is essential to assess the soft tissues on every chest X-ray you examine. You will often find important ...The walls of the diaphysis are composed of dense and hard compact bone. Figure 6.3.1 6.3. 1: Anatomy of a Long Bone.A typical long bone shows the gross anatomical characteristics of bone. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone.In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide.Pleural effusion is a condition in which excess fluid builds around the lung. Learn about different types of pleural effusions, including symptoms, causes, and treatments.This small structure is cartilaginous early in life, but gradually becomes ossified starting during middle age. Ribs. Each rib is a curved, flattened bone that contributes to the wall of the thorax. The ribs articulate posteriorly with the T1–T12 thoracic vertebrae, and most attach anteriorly via their costal cartilages to the sternum.Aug 30, 2018 · The skeletal system’s main function is to provide support for the body. For example, the spinal column provides support for the head and torso. The legs, on the other hand, support and bear the ... Osteocytes, bone cells like chondrocytes, are located within lacunae. The histology of transverse tissue from long bone shows a typical arrangement of osteocytes in concentric circles around a central canal. Bone is a highly vascularized tissue. Unlike cartilage, bone tissue can recover from injuries in a relatively short time.

The major respiratory structures span the nasal cavity to the diaphragm. Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. The conducting zone of the respiratory system includes the organs and structures not directly involved in gas exchange. The gas exchange occurs in the respiratory zone.

Symptoms often result from the tumor putting pressure on surrounding structures, like your heart, airway or spinal cord. Generally, children experience symptoms more commonly than adults. Malignant tumors cause symptoms more often than benign tumors. Symptoms of a mediastinal tumor may include: Hoarseness.Gross Anatomy of Bone. The structure of a long bone allows for the best visualisation of all the parts of a bone (Figure 7.2.1). A long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone.Structure of Bone Tissue. There are two types of bone tissue: compact and spongy.The names imply that the two types differ in density, or how tightly the tissue is packed together. There are three types of cells that contribute to bone homeostasis.Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells.Cortical bone is a dense and rigid layer of calcium-rich osseous tissue that makes up the outer layer of a bone, explains InnerBody.
