Myasthenia gravis is an autoimmune neuromuscular disease caused by defective nerve transmission to the muscles. It is first characterized by drooping eyelids and slack facial muscles. Autoantibodies block the attachment of acetycholine to acetycholine receptors. This interferes with transmission of the nerve impulse.
You can find a self-paced tutorial with questions on myasthenia gravis at this NIH website.
