myasthenia gravis
Noun: A chronic autoimmune neuromuscular disorder characterized by varying degrees of weakness of the skeletal (voluntary) muscles of the body. The primary symptom is muscle weakness that worsens during periods of activity and improves after periods of rest. This condition is caused by a breakdown in communication between nerves and muscles at the neuromuscular junction, often due to antibodies blocking or destroying acetylcholine receptors.
