What term describes the transmission of signals along a neuron?

• A. Synapse
• B. Nerve impulses
• C. Action potential
• D. Neurotransmitter release

Answer: (B)

Nerve impulse. The transmission of signals along a neuron is the rapid electrical signal that travels down the axon as the neuron fires. This propagation happens as an action potential—a wave of depolarization and repolarization—that moves along the membrane and carries the message from the cell body toward the axon terminals. The other terms refer to different parts of the process: a synapse is the gap where neurons connect, neurotransmitter release occurs at the synapse to pass the signal to the next cell, and the action potential is the electrical event that makes the nerve impulse possible.
