These spread along the muscle, where a tiny gap called neuromuscular junction (NMJ) is found between the end of each nerve fiber and the muscle surface.

Eye symptoms may manifest as drooping of the eyelids, blurred vision, or double vision. Other symptoms of myasthenia gravis include waddling or unstable gait, changes in facial expression, difficulty swallowing, impaired speech, shortness of breath, and weakness of the arms, hands, legs, and neck.
