Muscular dystrophy and myasthenia gravis are complicated conditions. According to the research, muscular dystrophy is a "group of familial disorders that cause degeneration of skeletal muscle fibers" (Carroll, 2008, p 1633). Many researchers believe that the different types are each caused by different biochemical defects. For example, Duchenne Muscular Dystrophy is thought t be the result of a single gene defect "thought to be caused by a deletion of a segment of deoxyribonucleic acid" (Carroll, 2008, p 1633). Similarly, Becker Muscular Dystrophy is also caused by deformities in the X-link. Different types of dystrophy affect different muscle groups. There is the example of scapuloperneal Muscular Dystrophy, which affects the facial and shoulder muscles. Myasthenia gravis is an autoimmune neuromuscular condition, caused by abnormal transmission of nerve impulses to the...
Normal communication is interrupted, where antibodies disrupt the flow of acetylcholine between nerves and muscles. It is also a condition which weakens the skeletal muscles, especially after activity. Smaller muscles, such as those involved with controlling facial expression, eye and mouth movement are often affected by the disease.
Osteoarthritis, rheumatoid arthritis, and gouty arthritis are different in terms of cause, clinical findings, and treatment. Osteoarthritis is often caused by normal wear and tear on joints. This type of arthritis is associated with aging bodies, but can also be cause by joint injuries sustained throughout life (Crowther-Radulewicz). Clinical studies have found that isolated joints become enlarged and hard on palpitations. Treatment is conducted with the use of NSAIDS. On the other hand, rheumatoid arthritis is
