Diseases that affect skeletal muscle - muscles that are connected to bones, like the biceps in the upper arm and quadriceps in the thigh - are often referred to as "myopathies." Myopathies can be caused by several different factors, including inherited genetic defects (e.g., the muscular dystrophies), endocrine or glandular defects, inflammation (e.g., polymyositis), or biochemical or metabolic abnormalities.
