Conduction of action potentials along an axon is termed saltatory conduction because the action potential
A)is dependent on the ions Na⁺ and K⁺,portions of salts.
B)appears to leap or jump from node to node.
C)is named after Johan Saltare,who first discovered it.
D)moves very rapidly down the axon.

Question

Quizplus · Accepted Answer

Saltatory conduction involves the action potential jumping or leaping from node to node along a myelinated axon, rather than propagating smoothly along the entire length of the axon. This is due to the insulation provided by the myelin sheath, which allows the action potential to "skip" between the nodes of Ranvier where ion channels are concentrated, speeding up the transmission of the signal.
