Gaps in the insulating material that surrounds axons are known as ____.
A) interpeduncular nuclei
B) nodes of Ranvier
C) myelin synapses
D) presynaptic terminals

Question

Quizplus · Accepted Answer

Gaps in the insulating material that surrounds axons are known as nodes of Ranvier. The nodes of Ranvier are essential for the propagation of nerve impulses along an axon. As the action potential reaches a node of Ranvier, it triggers the opening of voltage-gated ion channels and the regeneration of the action potential for continued conduction along the axon.
