Question

Quizplus · Accepted Answer

Myasthenia gravis is a rare autoimmune disease that affects the neuromuscular junction and causes severe muscle weakness and fatigue. It is caused by a blockage of acetylcholine, a neurotransmitter responsible for muscle contraction, at the motor endplate. This results in impaired communication between nerves and muscles, leading to reduced muscle function.
