Saltatory Conduction __________.Saltatory conduction __________Blank.Multiple Choiceis slower than conduction on an unmyelinated fiberis faster than conduction on an unmyelinated fiberoccurs only if nodes of Ranvier are lackingoccurs only if the myelin sheath is continuous

In what type of axon does saltatory conduction occur?Multiple ChoiceMyelinated axonsUnmyelinated axons

In __________Blank axons, impulse conduction is uninterrupted along the entire axon; while in __________Blank axons, action potentials only occur at nodes of Ranvier.Multiple Choicemyelinated; unmyelinatedunmyelinated; myelinated

Why is saltatory conduction along a myelinated axon faster than continuous conduction along an unmyelinated axon?Multiple ChoiceSince many more voltage-gated channels are located along a myelinated axon, the conduction rate all along the axon is more rapid than along an unmyelinated axon having fewer channels.Since the bioelectric current travels very fast along the membrane surfaces surrounded by myelin (under the Schwann cells), the overall impulse conduction rate is very rapid.The lack of myelin around unmyelinated axons causes them to be unable to conduct impulses; therefore the myelinated axons will have a faster impulse conduction rate.Since action potentials do not occur along with the areas of the axon membrane that are covered by myelin, myelinated axons have less membrane surface that will conduct the impulse.
