Deterioration in the myelin sheaths of motor axons to the lower leg would be expected to
A)remove the restraints to ion movement and speed up impulse transmission.
B)cause immobility of the leg due to cessation of impulses to leg muscles.
C)slow the rate of transmission and cause reduced motor control.
D)have little effect because the sheaths are for insulation only.
E)do none of these.

Question

Quizplus · Accepted Answer

Myelin sheaths are important for faster impulse transmission in motor neurons. Deterioration in the myelin sheaths would slow down the rate of transmission, causing reduced motor control.
