Myasthenia gravis (MG) is the archetype of B cell–mediated autoimmune disorders. The pathology of MG sets it apart from the bulk of autoimmune diseases because it is caused by autoantibodies with clear pathogenic effects. The hallmark features of MG, particularly fluctuating muscle strength, can be attributed to the unique pathophysiology of impaired neuromuscular transmission, which produces a dynamic disorder governed by the cycle of neuromuscular junction (NMJ) repair.

How much do you know about the physiologic mechanisms underlying MG? Test your knowledge with this quick quiz.
