What is the most common site for Mycobacterium tuberculosis in the bone Group of answer choices?

Of those cases, the spine is most commonly affected. Therefore, if you have bone TB, you are more likely to have it in or on your spinal column. However, bone TB could potentially affect any bone in your body. A common form of spinal bone TB is known as Pott's disease.

What is the most common site for Mycobacterium?

Although these bacteria are related to Mycobacterium tuberculosis, the species that causes tuberculosis, they are a distinct group of mycobacteria. The most common site of infection is the lungs.

Which type of fracture would have a linear fracture that occurs in a straight line across the bone?

Transverse fractures are breaks that are in a straight line across the bone. This type of fracture may be caused by traumatic events like falls or automobile accidents.

Which term would describe a broken bone in which the bone ends have failed to grow together?

A malunion fracture occurs when a large space between the displaced ends of the bone have been filled in by new bone.

What is the most common site for Mycobacterium tuberculosis in bone choice of answer choices vertebral column long bones hips ankles?

Approximately 10% of patients with extrapulmonary tuberculosis have skeletal involvement. The spine is the most common skeletal site affected, followed by the hip and knee.

Where can Mycobacterium be found?

Mycobacterium abscessus is a bacterium distantly related to the ones that cause tuberculosis and leprosy. It is part of a group known as rapidly growing mycobacteria and is found in water, soil, and dust. It has been known to contaminate medications and products, including medical devices.

What is the most common type of fracture?

The collarbone, or clavicle, is one of the most frequently broken bones. It's the most common type of fracture in children and teens. Seniors usually break their collarbones from a hard fall. Younger adults, teens, and children are more likely to break their collarbone in a car accident or from playing sports.

What is the most common bone to break?

Well, perhaps surprisingly, the most common bone to break is actually the clavicle, more often known as the collarbone. The clavicle is the bone that runs across the front of the body from shoulder to shoulder. Due to its length and slenderness, as well as its prominent position, it breaks quite easily.

What is the most common skull fracture?

The parietal bone is most frequently fractured, followed by the temporal, occipital, and frontal bones [10]. Linear fractures are the most common, followed by depressed and basilar skull fractures.

Which nerve is affected in Colles fracture?

A Colles' fracture is a type of fracture of the distal forearm in which the broken end of the radius is bent backwards. Symptoms may include pain, swelling, deformity, and bruising. Complications may include damage to the median nerve. It typically occurs as a result of a fall on an outstretched hand.

What is a compound fracture of the tibia and fibula?

The fibula helps stabilize the tibia but doesn't carry much weight. Although the tibia and fibula can break independently from each other, because they are so close together it is more common for both bones to break together. This is called a combined tibia-fibula fracture.

What causes bone malunion?

A malunion occurs when a fractured bone heals in an abnormal position, which can lead to impaired function of the bone or limb and make it look like it is 'bent'. Similarly, a nonunion is the result of a fractured bone failing to heal after an extended period of time – in some cases over a period of 9 to 12 months.

Where are mycobacterial species commonly found in nature?

NTM typically occur in natural water (von Reyn et al., 1994), drinking water distribution systems (Covert et al., 1999; Le Dantec et al., 2002), soils (Iivanainen et al., 1997) and dust.

What is Mycobacterium cell wall?

The cell wall is a giant tripartite complex composed of the outer membrane, the so-called mycomembrane (MM), arabinogalactan (AG) and peptidoglycan (PG). The inner leaflet of the MM is made of very long-chain fatty acids (mycolic acids) esterifying AG, which in turn is covalently attached to PG.

What characteristic is unique to Mycobacterium?

Tuberculosis is caused by Mycobacterium Tuberculosis H37Rv (MTB) which is a unique acid fast gram positive bacterium. It is unique because of its high lipid and mycolic acid content of its cell wall. It neither contains phospholipid outer membrane nor retains dye.

What is special about mycobacteria?

Mycobacterium species, including the human pathogen Mycobacterium tuberculosis, are unique among Gram-positive bacteria in producing a complex cell wall that contains unusual lipids and functions as a permeability barrier.

What is the process of converting painful stimuli into neuronal action potentials at the sensory receptor?

The process of converting painful stimuli into neuronal action potentials at the sensory receptor is termed: Transduction is the process of converting painful stimuli into neuronal action potentials at the sensory receptor. A patient is diagnosed with dementia.

Where does osteosarcoma occur?

It occurs in young adults from age 10 to 30 or in adults 60 to 70 years of age. It occurs in the metaphyseal region of long bones.

What cells produce rheumatoid factor antibodies?

B cells produce rheumatoid factor antibodies against the IgG antigens to form the immune complex. In rheumatoid arthritis, the T lymphocytes and macrophages are activated by an unknown trigger. Tumor necrosis factor-α as well as other proinflammatory cytokines within the synovium also cause damage.

What is the blood flow through the brain?

Autoregulation is the process by which the blood flow through the brain is regulated. Normally the vessels respond to metabolic factors, including pH, carbon dioxide, and oxygen levels. Blood flow is maintained from a range of mean arterial pressure of 50 to 150 mm Hg. Hypotension predisposes to ischemia.

Is Becker muscular dystrophy inherited?

Becker muscular dystrophy is inherited, but is caused by the production of a reduced amount of an abnormal dystrophin protein and a slower muscular degeneration. Facioscapulohumeral muscular dystrophy is rare and is autosomal dominant. It affects the muscles of the shoulder girdle and the face.

Which bones are most likely to be metastasized?

vertebral bodies. The most common sites for bone metastases include vertebral bodies , the pelvis, the proximal ends of the femur and humerus, and the ribs. Midshaft femurs, carpal bones, and the radius are not common sites for bone metastases.

Where is chondroma found?

They commonly occur between the ages of 20 and 40 years. Chondroma is a cartilage-forming tumor located within the bone and can be located within the medullary cavity of the bone. A 25-year-old athlete reports a sudden popping sound in the knee.

What is the cause of rickets?

Osteoporosis is caused by age, genetics, estrogen, and certain risk factors. It generally affects individuals older than 60 years. Osteomalacia is the adult form of rickets and is always caused by inadequate concentration of calcium or phosphorus in the body.

Is Becker muscular dystrophy inherited?

Becker muscular dystrophy is inherited, but is caused by the production of a reduced amount of an abnormal dystrophin protein and a slower muscular degeneration. Facioscapulohumeral muscular dystrophy is rare and is autosomal dominant. It affects the muscles of the shoulder girdle and the face.

Is there a skin thickening with deposition of connective tissue?

There is skin thickening with deposition of connective tissue. There is skin thickening with deposition of connective tissue. Scleroderma is a multisystem, inflammatory, connective tissue disease characterized by skin thickening and deposition of large quantities of connective tissue.
