The extension of the neuron called an "axon" carries the electrical impulses from the cell body to another extension called an "axon terminal".

The nervous system is made up of nerve cells called neurons. These neurons carry electrical impulses from extensions called axons, through the cell body, to one extension called an axon terminal.

The extension of a neuron that carries electrical impulses away from the cell body is called an axon. Axons are long, slender projections that transmit signals, known as action potentials, to other neurons, muscles, or glands. These impulses travel along the axon until reaching the axon terminal, where they can be transmitted to other neurons or effector cells.

Now, to answer your question directly, the correct term for the particular extension of a neuron that carries an electrical impulse away from the cell body is an axon.
