 | | The name myasthenia gravis, which is Latin and Greek in origin, literally means "grave muscle weakness." With current therapies, however, most cases of myasthenia gravis are not as "grave" as the name implies. |
 | | The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest. |
 | | In myasthenia gravis, antibodies block, alter, or destroy the receptors for acetylcholine at the neuromuscular junction which prevents the muscle contraction from occurring. |
