Saltatory conduction
A)occurs in unmyelinated nerve fibers
B)is slower than contiguous conduction because myelin acts as an insulator to slow the impulse
C)involves the impulse jumping from one node of Ranvier to the adjacent node
D)refers to the action potential spreading from one Schwann cell to the adjacent Schwann cell
E)occurs along dendrites and axons of certain neurons

Question

Quizplus · Accepted Answer

Saltatory conduction refers to the impulse jumping from one node of Ranvier to the adjacent node, which occurs in myelinated nerve fibers. It is faster than contiguous conduction because the myelin acts as an insulator, which prevents current leakages and allows the impulse to jump between nodes, thus reducing energy expenditure by the neuron.
