Saltatory conduction
A) is called "saltatory" because it is caused by sodium chloride.
B) is much slower than nonsaltatory conduction.
C) occurs only in the dendrites.
D) occurs only in the axons.

Question

Quizplus · Accepted Answer

Saltatory conduction refers to the rapid jumping of an action potential from node to node along myelinated axons, which is faster than the continuous propagation of action potentials in unmyelinated axons. Therefore, it occurs only in the axons. Choice A is incorrect because saltatory conduction is caused by the movement of sodium ions, not sodium chloride. Choice B is incorrect because saltatory conduction is faster than nonsaltatory conduction. Choice C is incorrect because dendrites are usually unmyelinated and do not allow saltatory conduction.
