Action potentials travel swiftly down:
A) dendrites with myelin and more slowly in dendrites without myelin.
B) axons without myelin and more slowly in axons with myelin.
C) dendrites without myelin and more slowly in dendrites with myelin.
D) axons with myelin and more slowly in axons without myelin.

Question

Quizplus · Accepted Answer

Action potentials travel swiftly down axons with myelin due to the insulation provided by the myelin sheath. This insulation allows for the action potential to "jump" from one node of Ranvier to the next, resulting in faster transmission. In contrast, axons without myelin have slower transmission rates.
