Question

I am a way of coding information by allowing information to be transmitted both quickly and accurately by electrical means. Who am I?

• A. Nerve code
• B. Reflex arc
• C. Nerve impulse
• D. Brain signal

Answer 1

The correct option is C

Nerve impulse

Nerve impulses are a way of coding information, in a similar way to FM radio, allowing information to be transmitted both quickly and accurately. Nerve impulses are transmitted through change in the concentration of sodium ions on the surface of nerve cell which happens on receiving a stimulus by receptors and then by the dendrites of neurons.
