The nodes of Ranvier are:
A)a type of neuron that communicates information from one neuron to another.
B)the synaptic vesicles that contain neurotransmitters.

D)small gaps in the myelin sheaths that cover some axons.

Question

Quizplus · Accepted Answer

The nodes of Ranvier are small gaps in the myelin sheaths that cover some axons. They are essential for the conduction of nerve impulses along the axon. At each node of Ranvier, the action potential is regenerated, which allows for saltatory conduction, a fast and efficient mode of nerve impulse transmission.
