Final answer:
Neurons are electrically excitable cells that transmit nerve impulses through electrical signals. However, neurons do not produce electrical or magnetic effects outside the body.
Step-by-step explanation:
Neurons, or nerve cells, are electrically excitable cells that transmit nerve impulses. The transmission of nerve impulses occurs through electrical signals generated within the neuron. Despite generating a small amount of electricity, neurons do not produce electrical or magnetic effects outside the body. The electrical charge within the neuron is a result of differences in electrical potential across the plasma membrane and the movement of ions.
