Myasthenia gravis is an autoimmune disorder that affects the neuromuscular junction, interfering with the transmission of acetylcholine, leading to weakness of voluntary muscles. It does not typically present as ascending paralysis starting in the legs (which is more characteristic of Guillain-Barré syndrome) nor is it usually preceded by a viral infection.
