Which statement best describes the function of neurons?

• A. Transmit information as electrical impulses
• B. Produce hormones
• C. Store fat
• D. Regulate body temperature

Answer: (A)

Neurons specialize in signaling messages throughout the nervous system. They generate and transmit information as electrical impulses—action potentials—that travel along the neuron and trigger chemical signals at synapses to pass the message to other neurons, muscles, or glands. This rapid, directional communication is the core job of neurons, allowing senses, movement, and thought to unfold.

Producing hormones is the function of endocrine glands, though some neurons can release neurohormones in certain contexts, it isn’t their primary role. Storing fat is done by adipose tissue, not neurons. While brain regions with neurons regulate temperature, the basic activity of neurons is to carry and convey information through electrical signaling, which is why that statement best describes their function.
