A demyelinating disease (such as MS) slows down or prevents action potentials along motor neurons. Using this information, would a demyelinating disease cause skeletal muscle to stay constantly contracted (in tetanus), or not contract at all (in flaccid paralysis) ?

Flaccid paralysis.

Explanation:

Demyelinating disease may be defined as in which the protective layer of myelin sheath gets damaged. This causes the slow down or even stops the transfer of nerve impulse.

Flaccid paralysis is the neurologic condition that results in the reduced muscle tone due to damage in the nerves of the muscles. The contraction is inhibited in the flaccid paralysis. The demylination results in no contraction at all as occur in flaccid paralysis.

Thus, the answer is flaccid paralysis.
