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) Neural signaling may not work properly as a result of nervous system demyelination.
C) The fibers of the axons are enlarged, slowing the neural transmission.
D) The neurons have degenerated and are no longer producing neural transmission.

Multiple sclerosis is a disease that attacks the myelin sheaths that surround axons in the nervous system. Demyelination can cause disruptions in neural signaling and can lead to a reduction in sensation in distal parts of the body.
