Here's why:

* Neurons: These are the basic building blocks of the nervous system. They are specialized cells that transmit information throughout the body.

* Axon: This is a long, slender projection that extends from the neuron's cell body. It acts like a "cable" that carries electrical signals (action potentials) away from the cell body.

* Synapse: At the end of the axon, there's a specialized junction called a synapse. Here, the signal is transmitted to another neuron, muscle cell, or gland cell.

In summary: The neuron's axon carries signals from the cell body to the synapse, where it can be transmitted to an organ, muscle, or another neuron.
