Conduction of action potentials in an unmyelinated axon is referred to as
A) absolute.
B) relative.
C) saltatory.
D) passive.

Question

Quizplus · Accepted Answer

Conduction of action potentials in an unmyelinated axon is passive, as the action potential spreads passively along the entire length of the axon, without any intervention or boost from specialized structures such as ion channels or myelin sheaths. In contrast, myelinated axons use saltatory conduction, where the action potential "jumps" from node to node, allowing for faster conduction speeds. "Absolute" and "relative" refer to the refractory periods during and after an action potential, respectively, and are not directly related to conduction in unmyelinated axons.
