Myasthenia gravis (from Greek μύς `muscle`, ἀσθένεια `weakness`, and gravis `serious`; abbreviated MG) is an autoimmune neuromuscular disease leading to fluctuating muscle weakness and fatigue. Muscle weakness is caused by circulating antibodies that block acetylcholine receptors at the postsynaptic neuromuscular junction, inhibi...

A disease in which acetylcholine receptors on the muscle cells are destroyed, so that muscles can no longer respond to the acetylcholine signal in order to contract. Symptoms include muscular weakness and progressively more common bouts of fatigue. Its cause is unknown but is more common in females than in males and usually strikes between the ages...

The characteristic feature of the disease is easy fatigue of certain voluntary muscle groups on repeated use. Muscles of the face or upper trunk are especially likely to be affected. In most, and perhaps all cases due to the development of autoantibodies against the acetylcholine receptor in neuromuscular junctions. Immunization of mice or rats with this receptor protein leads to a disease with the features of myasthenia.
