your comment is aiaa
your comment is aiaatwngmoderition. I don't know what that means so I will do another reflectionassignment of module 12 to be on the safe side.There are two subjects on module 12 Iwill discuss. Myasthenia gravis and musculardystrophy.Myasthenia gravis is an uncommon condition that causes certain muscles tobecome weak. With treatment, most people live a normal life. Myasthemiagravis means grave muscle weakness'. The condition can affect any musclethat you control voluntarily, such as the heart muscle, are not affected.Myasthenia gravis most commonly affects the muscle that control eye andeyelid movement, facial expression, chewing, swallowing and talking, andthe muscle in the arms and legs. Less often the muscle involved in breathingmay also be affected. The muscle weakness is usually made worse by physicalactivity and improved by rest. Myasthenia gravis affects 3 per 10,000 andoccurs more frequently among women than men. No risk factors are known.Myasthenia gravis is an autoimmune disease, which means that your immunesystem attacks your own body tissues. In the case of myasthenia gravis,your immune system produces antibodies that block or damage your musclereceptor cells. This blocks the messages that pass from the nerve endings tothe muscle, so your muscle do not contract well and become weak. The reasonwhy some people's immune system make antibodies against muscle receptorcells is not fully understood. Many people with myasthenia gravis becomecompletely free of symptoms with traetment. Sometimes, the symptomsmay stop alltogether and you can cone off treatment. Treatment includesdrugs that increase acetycholine levels at the myoneural junction. The thymusgland, which is involved in the immune response, is often enlarged in myastheniagravis patients. Removal of this gland sometimes brings about a remission butnot a cure.The term muscular dystrophy includes several forms of the disease, all of whichare hereditary. The various forms are transmitted differently and affectdifferent muscles, but all forms result in muscle degeneration, which totallydisables the individual. The most common and serious type is Duchenne,which is caused by a sex-linked gene and affects approximately 2 per 10,000people. Muscular dystrophy can appear at any age, but generally signsappear in the third to fifth year. In Duchenne's muscular dystrophy acytoskeletal protein called dystrophin is missing. As a result of this defect,muscle fibers die and are replaced by fat and connective tissue. Becauseneither of these tissues has the ability to contract, skeletal muscles weaken.I want to comment on the Jerry Lewis MDA Telethon. The MDA Telethonstarted in the 1950 s or 1960 s and they have raised $2.45 billion since itsinception, but with their $2.45 billion they raised they have not found a curefor muscular dystrophy. Hopefully they at least found a palliative orsymptomatic treatment for muscular dystrophy with the $2.45 billionthey have raised
