Which cells transmit information as electrical impulses?

Which cells transmit information as electrical impulses?

• A. Dendrites
• B. Neuroglia
• C. Axons
• D. Neurons

Answer: (D)

Information transmission as electrical impulses is a defining feature of neurons, the specialized cells of the nervous system. A neuron receives signals through its dendrites, processes them in the cell body, and then sends a rapid electrical signal called an action potential along its axon to communicate with other neurons or muscles. Neuroglia (glial cells) support and protect neurons but do not generate or propagate these impulses. Dendrites are the receiving branches that bring in signals, while the axon is the long carrier that transmits the impulse away from the cell body. So the cell that transmits information electrically is the neuron.
