[Campbell Biology P.1116] Which statement accurately describes electrical signaling along an ... | Practice Question

Which statement accurately describes electrical signaling along an axon, according to the diagram's description?

  • A: Electrical impulses travel in multiple directions along the axon.
  • B: The strength of each electrical impulse varies significantly.
  • C: Electrical impulses are identical, but their frequency of signaling can vary.
  • D: Axons primarily receive input from other neurons.

Explanation

The section "Electrical signaling along axon" clearly states: "Electrical impulses travel in one direction only. Every impulse is identical, but the frequency of signaling varies." This directly supports option C.
