EXPLAIN
The made-up drug leakyhose degrades myelin resulting in myelin becoming more porous and therefore a poor insulator.
2.) Which of the following would NOT be an effect of leakyhose?
A. Propagation of the action potential would likely slow
B. The action potential may degrade because it can’t properly be regenerated
C. The action potential would not propagate but would rather reverse directions
D. Saltatory conduction may be disrupted
E. All of the above effects are consistent with the administration of leakyhose
