  1. Question 1

    Q1. In myelinated neurons, the nerve impulse travels significantly faster by jumping from one non-myelinated gap to the next. What are these gaps called?

    • A) Schwann cells
    • B) Nodes of Ranvier
    • C) Myelin sheaths
    • D) Synaptic knobs

    Answer: Nodes of Ranvier

    Explanation: Nodes of Ranvier are the gaps where saltatory conduction occurs; Schwan cells fail because they are the cells that form the myelin.
