What are the small gaps that interrupt the myelin sheath of neurons at intervals of 1 to 2 μm?Multiple choice question.Gray matterNodes of RanvierVoltage-gated channels

The myelin sheath along an axon is not continuous. What are the gaps between Schwann cells called?Multiple ChoiceAxon terminalsNodes of RanvierCollateralsAxon hillocks

What would happen if there were no gaps between the segments of myelin?

Nodes of Ranvier representGroup of answer choicespoints where two axons connect.gaps in myelin wrapping.areas of high synaptic density.segments of axon where only K+ channels are located.segments of axon where passive current flows.

What would happen if there were no gaps between the segments of myelin?Group of answer choicesThe propagation of action potentials would slow down.Action potentials could not travel to the axon terminals.The axon would be rigid making the spine inflexible.The neuron would die because the axon could not “breath”.The propagation of action potentials would speed up.Next

Which of the following does not influence the time necessary for a nerve impulse to be transmitted? diameter of the axon length of the axon presence or absence of a myelin sheath presence or absence of nodes of Ranvier whether or not the impulse begins in the CNS
