What are the small electrical impulses that organize and conduct messages between nerve cells?

• A. Nerve impulses
• B. Nerve cells
• C. Neurotransmitters
• D. Synapses

Answer: (A)

Electric signaling in the nervous system happens through nerve impulses, the brief electrical spikes that organize and carry messages between neurons. These impulses travel along a neuron’s membrane and, as they reach the end of the cell, they usually trigger the release of neurotransmitters at the synapse to pass the signal to the next neuron. Nerve cells are the cells that generate and transmit signals, neurotransmitters are the chemical messengers used at the junction between neurons, and synapses are the contact points where communication occurs. The phrase describes the actual electrical signal driving neural communication.
