Action potentials travel along the
A) axon membrane.
B) dendrite membrane.
C) cell body.
D) myelin.

Question

Quizplus · Accepted Answer

Action potentials are propagated along the axon membrane due to the presence of voltage-gated ion channels that allow for the rapid inflow and outflow of ions, resulting in a rapid depolarization and repolarization of the membrane potential. Dendrites and the cell body do not have voltage-gated ion channels and are not involved in the propagation of action potentials. Myelin is involved in the propagation of action potentials but does not actually conduct the electrical signal; instead, it helps to increase the speed of conduction by allowing the action potential to "jump" from one node of Ranvier to the next.
