The main function of the muscular system is to provide movement for the body. They muscular system is made up of three types of muscles: skeletal, smooth and cardiac. Skeletal muscle is the voluntary muscle whose movement can be controlled, smooth muscle is the muscle that makes up the internal organs and cardiac muscle is only found in the heart. Problems with the muscular system most often affect the skeletal muscle, but can affect any of the types.
Fibromyalgia
Fibromyalgia is a chronic condition in which there is a constant feeling of pain in the muscles, tendons and ligaments. In addition to pain, the affected person experiences constant fatigue and tender points on the body. Tender points are areas where a small amount of pressure can cause a great deal of pain. The exact cause of fibromyalgia is unknown, but a combination of genetics, infections and physical or emotional trauma are thought to play a role in the development of the disease, according to MayoClinic.com. Treatment for fibromyalgia consists of medications to reduce pain and aid in sleep and physical therapy.
Polymyositis
Polymyositis is a muscular system disease characterized by chronic inflammation of the skeletal muscles, which causes them to become increasingly weak. The weakness usually starts in the muscles located closest to the body and then moves out to the muscles in the arms and legs, according to the National Institute of Neurological Disorders and Stroke. This leads to difficulty walking, getting up from a sitting position and reaching overhead. Other symptoms of polymyositis include arthritis, shortness of breath, difficulty speaking and heart arrhythmias. Polymyositis is most often treated with anti-inflammatory drugs and physical therapy. Occasionally, immunosuppressant drugs and heat therapy may be used to reduce symptoms.
Duchenne Muscular Dystrophy
Duchenne muscular dystrophy is a genetic disorder that is caused by a defective gene for one of the proteins found in muscle, which is called dystrophin. Duchenne muscular dystrophy is characterized by progressive muscle weakness and is the most rapid form of muscular dystrophy. Muscle weakness usually begins in the legs and pelvic area and then progresses to the arms and neck, according to MedlinePlus. In addition to muscle weakness, other symptoms of Duchenne muscular dystrophy include fatigue, difficulty with motor skills, mental retardation and difficulty walking. Treatment for Duchenne muscular dystrophy consists of physical therapy and the use of braces and wheelchairs, in severe cases.
