Which of the following describes saltatory conduction
A)occurs in unmyelinated nerve fibres
B)is slower than conduction by local current flow because the 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

Question

Quizplus · Accepted Answer

Saltatory conduction refers to the impulse jumping or "leaping" from one node of Ranvier to the adjacent node. This occurs in myelinated nerve fibres and is faster than conduction by local current flow because the myelin acts as an insulator to prevent the impulse from dissipating. The action potential does not spread from one Schwann cell to the adjacent Schwann cell.
