The nodes of Ranvier are:
A)a network of fibers within the medulla associated with attention and alertness
B)tiny areas on the surface of the soma that are sensitive to neurotransmitters
C)small sacs found in the axon terminal that store neurotransmitters
D)gaps in the myelin sheath that allow the neural signal to travel at a greater speed

Question

Quizplus · Accepted Answer

The nodes of Ranvier are gaps in the myelin sheath that allow the neural signal to travel more quickly down the axon. They facilitate saltatory conduction, where the nerve impulse "jumps" from node to node, rather than traveling continuously along the entire length of the axon.
