Question 1

In multiple sclerosis, there is progressive and intermittent damage to the myelin sheath of central axons. One symptom is poor motor control of the affected area. Why does destruction of the myelin sheath affect motor control?

Question 2

Multiple sclerosis (MS) is one of the better studied diseases resulting from demyelination of axons (in MS, only CNS axons are affected). Some of the earliest symptoms of the disease are difficulty in focusing the eyes, such as in reading, and difficulty in maintaining balance, and frequently not being able to make adjustments in posture to avoid falling. How do these symptoms "fit" with what you know about nerve impulses, myelin sheaths, and the location of gated ion channels in the membranes of axons?
