Refer to the graph above.If the myelin fibers were stripped from this membrane,you would expect the action potential cycle to go
A)much faster than depicted in the graph.
B)much faster than normal but not peak at 30 mV.
C)slower than depicted in the graph.
D)much slower than normal but peak much higher than 30 mV.
E)none of the above

Quizplus · Accepted Answer

Myelin fibers act as insulation around the axon, which allows for saltatory conduction and thus speeds up the action potential cycle. Without myelin fibers, the action potential would have to propagate through the entire length of the axon, leading to a slower propagation speed compared to the depicted graph.
