In some (although not all)cases of multiple sclerosis,one of the first symptoms noticed is a reduction in sensation from distal parts of the body,such as feet and hands.Which of the following statements best explains why this might happen?
A) The fibers of the axons are reduced in diameter,so the information can't travel fast enough.
B) Without the myelin sheath covering the axon,the neural transmission from the periphery is slowed.
C) The fibers of the axons are enlarged,slowing the neural transmission.
D) The neurons have degenerated and are no longer producing neural transmission.
