Question

Quizplus · Accepted Answer

The weakness resulting from the segmental paresis and paralysis characteristic of anterior horn cell injury is difficult to recognize because two or more nerve roots supply each muscle. Many diseases do cause weakness and fatigue, but this answer is not specific for ALS. ALS involves both upper and lower motor neurons. The disease involves a disturbance in motor, not sensory function.
