What is myasthenia gravis?
Myasthenia gravis (pronounced My-as-theen-ee-a grav-us) comes from the Greek and Latin words meaning “grave muscular weakness.” The most common form of MG is a chronic autoimmune neuromuscular disorder that is characterized by fluctuating weakness of the voluntary muscle groups.
