A wave of electrochemical changes, which travels along the length of the neuron involving chemical reactions and movement of ions across the cell membrane, is:
Correct answer: C. Nerve impulse
- A. Membrane potential
- B. Resting membrane potential
- C. Nerve impulse
- D. Electron pump
Explanation
A nerve impulse is the travelling wave of electrical and chemical changes produced by ion movement across the neuron's membrane. A membrane potential is a voltage difference at a particular membrane state, not necessarily a travelling signal.
