The extension of a neuron that carries the impulse to another cell is called what?

• A. Dendrite
• B. Soma
• C. Axon
• D. Synapse

Answer: (C)

The extension that carries the impulse away from the neuron’s body to another cell is the axon. It serves as the main output pathway, conducting the electrical signal, the action potential, along its length until it reaches the axon terminals that release neurotransmitters across the synapse to the next cell. Dendrites are the receiving branches, gathering signals from other neurons, while the soma is the cell body that houses the nucleus and metabolic machinery. The synapse is the junction where communication occurs between neurons, not the extending cable that transmits the impulse itself.
