Diseases of the muscular system

Myopathies are diseases of skeletal muscle which are not caused by nerve disorders. These diseases cause the skeletal or voluntary muscles to become weak or wasted. Myopathies are usually degenerative, but they are sometimes caused by drug side effects, chemical poisoning, or a chronic disorder of the immune system.

Chronic fatigue syndrome is an illness characterized by prolonged, debilitating fatigue, nonspecific symptoms such as headaches, recurrent sore throats, muscle and joint pains, memory and concentration difficulties. Chronic fatigue syndrome is a debilitating and complex disorder characterized by profound fatigue of six months and multiple.

Fibromyalgia is a debilitating chronic illness characterized by diffuse pain, fatigue, and a wide range of other symptoms. It is a syndrome, not a disease. It is not contagious, and is probably genetic. It affects more women than men, mostly between ages 20 and 50. It is seen in 3-10% of the general population.

Muscular dystrophy is a broad term that describes a genetic disorder of the muscles. Muscular dystrophy causes the muscles in the body to become very weak. The muscles break down and are replaced with fatty deposits over time. Muscular dystrophy is a genetic disorder that is characterized by muscle wasting and weakening.

Dermatomyositis is one of a group of inflammatory muscle diseases. It is a subtype of inflammatory muscle disease. Dermatomyositis may affect people of any race, age or sex, although it is twice as common in women than in men. Dermatomyositis belongs to a group of conditions called inflammatory myopathies.

Polymyositis is a systemic connective tissue disorder characterized by inflammatory and degenerative changes in the muscles, leading to symmetric weakness and some degree of muscle atrophy. Polymyositis is slightly more common in females. It affects all age groups, although its onset is most common in middle childhood and in the twenties.

Skeletal System

The skeletal system consists of bones, ligaments, and cartilages. Your body has over 200 bones, each serving many purposes. Bones serve as a framework for your body. Your bones work in harmony with your muscles. Bones also protect you. Your ribs and breastbone protect your heart and lungs. The bones of your skull protect your brain. Because of the muscles and many small bones in your hands and fingers, you can handle objects with ease and skill. Bone marrow is a special kind of tissue in the hollow center area of some bones. Red blood cells are produced in marrow.

When you were born, your skeletal system was not as strong as it is now. At birth, most of your skeletal system was composed of cartilage. Cartilage is connective tissue that is rigid but softer than bone. As you grew older, ossification took place. Ossification is a process by which bone cells and minerals replace cartilage. This process continues through childhood and into early adulthood. However, even after ossification is complete, some body parts remain as cartilage. The tip of your nose and the outside of your ears contain cartilage.
