  • Imagine two neurons of the same length are tasked with sending an electrical signal. Neuron A's axon is coated with a thick, fatty substance that acts as an insulator. Neuron B's axon lacks this coating. Which of the following statements most accurately predicts the functional difference between these two neurons?

  • Neural Signal Transmission Impairment

  • Neurological Effects of Phenylketonuria (PKU)
